First, lithium is generally considered no memory effect, which is the manufacturer of the product. Lithium batteries still have memories, but only slightly than the nickel-metal hydride sony vgp-bps9 battery. If the long-term use of all right to charge method, lithium battery memory effect will be severe. Therefore, the lithium batteries run out and then still have to take charge method to ensure the use of time two, there can be reactivated memory phenomenon. The key here is how to discharge. Must not seek the easy way first to the battery terminals with a wire shorted, this will cause damage to the HP pavilion n5470-f2407m battery! Some chargers have a discharge function, but this method also has drawbacks. Its discharge current larger than the current phone, which also have damage to the Universal External Battery. Besides can not determine whether the electric discharge end. The best way is to use the phone a natural discharge, which of course takes time. Pumping a mobile home on weekends when not in use, turn so that the phone is in standby mode, and so on its own power on-off discharge. Usually repeated several times immediately after the boot can not be opened, and then do not think that has been discharged, the phone should be placed for some time and then boot. This repeated discharge until the phone is still not put more than an hour longer boot, even if the basic conclusion of the discharge. Charging new phone activation method and bought the same way when the first charge more than ten hours, and then added charge two to three hours. If you have time, make additional charge can be repeated two or three times. Third, do not wait until the phone with a very short time reduced to the activation do, so because of lack of time caused by inadequate discharge, the dell inspiron 14 battery 's memory still remains. Will still be activated using a very short time. Best use of time is shortened to take active measures. Use of mobile phones such as the new time is seven days, when using the time down to about four days to do on the activation. This weekend you can easily finish the activation. Fourth, sometimes bought or re-activate the new phone not long after the apparent decline in use of time, then is not necessarily a memory effect, which may be caused by poor contact. Best to re-activate the phone before the battery for acer travelmate 4651lci contacts and do a make clean swabbing: a small cotton swab or toothpick wrapped with paper towel dipped a little alcohol swabbing on it. Must not use a hard object to scratch, but will increase as bad. No alcohol can be highly liquor instead. Use paper towel immediately after swabbing paint dry, to avoid excess alcohol causing open circuit between the battery terminals. Fifth, sometimes the xps m1330 battery does not identify the emergence of space there is no power or memory effect, it may be the identity function cell phone battery problems. This usually occurs after a period of time on the phone to determine the solution is simple: when there is a space, do not charge right away, wait to see whether the phone automatically shut down soon. Of course, no need to check every time, over a period of time to pay attention to what is necessary. Otherwise, the battery will speed up the memory effect. Of course, not all phones will appear this situation. Sixth, mobile phone sony vaio pcg-961a battery is the soft underbelly, which is the mobile phone in all parts of the shortest life expectancy. Unfortunately, it is difficult to buy to replace the original battery.
Edit this paragraph mobile phone battery charging techniques
Mobile phone battery (5) 1, if we want to extend the battery's effective use of time, in addition to the quality of the charger should be guaranteed, the correct charging technique is also essential, because the poor quality of the charger or charging the wrong methods will affect hp compaq business notebook nx7400 battery life and cycle life, here I sorted out the charging techniques: 2, buy a new phone if the battery is nickel-metal hydride battery, then charge 3-5 times before the adjustment period is generally known, should be charged 14 hours above, to ensure the full activation of the activity of nickel-metal hydride batteries. Lithium ion batteries have no memory effect, but there is a strong inert, should be fully activated in order to ensure the future use to achieve the best performance. 3, Some automated intelligent rapid charger when the lights change, said only 90 percent full. Charger will automatically change with the slow charging the GATEWAY M505 Laptop AC Adapter battery is full. Best use of the battery is full, otherwise it will reduce the use of time. 4, before charging, lithium batteries do not need special discharge, discharge improper battery will be damaged. 5, charging as much as possible to slow enrich my knowledge, to reduce the fast charge mode; time should not exceed 24 hours. 6, after three to five times the SAMSUNG Portable DVD Batteries fully charge and discharge cycles of its internal chemical substance will be all "activated" to achieve the best results. 7, please use the original or reputation of a good brand chargers, lithium batteries use lithium battery charger, and follow the instructions, otherwise it will damage the battery, or even dangerous. 8, there are many users did not notice or do not understand I do not know, often in charge Shihai the phone open, in fact, it will hurt the mobile phone life very easily, because in the charging process, the mobile phone circuit boards will be fever, at this time if There are external phone, may produce an instant return current, the phone's internal parts damage. 9, the SAMSUNG X05-000 Battery life depends on the number of repeated charge and discharge, it should try to avoid charging the battery is more than power, it will shorten battery life. Phone off more than 7 days, should be the first mobile phone battery is fully discharged, adequate electricity and then use. 10, there is cell phone battery self-discharge Ni-MH battery when not in a day by about 1% of the remaining capacity of the discharge, lithium SONY NP-FP50 Battery by 0.2-0.3% a day discharge. 11, charging the battery, try to use a dedicated outlet, do not share the charger socket with TV and other appliances. 12, although our phones within the network coverage area, but the phone off charge, we have been unable to accept phone and dial the phone. At this point, we can use the phone did not pass transfer function, will be transferred to the side of the fixed-mobile phone to prevent calls lost, this method for the mobile phone network coverage area or signal is weak and can not be connected when they apply. 13, do not expose the Acer Aspire 5235 Battery to heat or cold, like a dog day, not the phone in the car, stood in the scorching sun exposure; or get air-conditioned room, where on the air blowing straight. When charging, the battery a little heat is normal, but can not make it hot Jinshou "suffering." To avoid this from happening, it is best at room temperature for charging, and do not cover anything on that machine. 14, nickel-cadmium (NiCd) batteries must be guaranteed before the battery is fully discharged, then charge must ensure that the Sony Dslr-a300k/N Battery is fully charged. 15, if the phone battery is too long without use, it is best to apply to cell phone maintenance department for an activation process, you can own a DC barostat, adjust voltage 5-6V, current 500-600mA reverse Connect the SONY VAIO PCG-F240 Adapter battery. Note that touch open up to repeat three times, it can be, after such treatment, then the original charger "adjustment" charge. 16, the charge is not longer, and there is no protection circuit of the battery is full charge should be stopped immediately, otherwise the battery overheating due to heat or impact performance. 17, dedicated lithium-ion battery charger must be selected, or they might not reach saturation, impact on its performance. After charging, the charger should avoid placing more than 12 hours or more, long-term without the SAMSUNG VP-D361 Multi-Chargers battery and the phone should be separated. In the use of lithium batteries should be noted that after a period of time the battery is placed into hibernation, lower than normal capacity at this time, the use of time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle battery can be activated to restore normal capacity. Because lithium own characteristics, its decision is almost no memory effect. Therefore, users of the new lithium SAMSUNG ES55 Charger battery in the phone activation process does not require special methods and equipment. Not only the theory that, from my own practice, from the outset, using the standard method of charging that "activation" is the best. For lithium batteries, "activate" problem, many say is: the time to charge more than 12 hours, repeated three times to activate the battery. This "three times before charging more than 12 hours to charge," was obviously from the nickel SONY VAIO PCG-F240 Adapter battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that the beginning of miscommunication. Lithium and nickel battery charge and discharge characteristics of a very big difference, and can tell you very clearly, I had access to all official technical information seriously stressed over charge and over discharge lithium Sony CCD-TRV59E Charger batteries, especially lithium liquid ion battery causing great harm. The standard charge and therefore the best time and the standard method of charging, in particular for not more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard charging method.
For lithium batteries, "activate" problem
Into the hands of the user is already activated the battery, because Canon Eos 1100d Battery manufacturers in the production of batteries there during this process. Called "into." Is active meaning.
Time to charge more than 12 hours of the problem
Fact is of no use, mobile phone battery is protected with a board and this protection board will automatically power off when the conditions are. A. overcharge protection is the battery is full it will automatically stop charging. B. over-discharge protection . is to use a 3.2V battery will automatically stop the discharge. C. Short circuit protection is accidentally short-circuit the Hi-Grade Notino AS7400 Adapter battery is automatically disconnected. That is the general charge the battery in about 2-3 hours on full. full after the actual charging circuit has been disconnected, so no sense.

UPS battery capacity and discharge rate impact analysis
When the UPS battery manufacturers in the configuration, the selected design capacity is not fully meet or exceed the load capacity and power supply power supply requirements of the time, but UPS put into operation, users often find in the city after the UPS does not power outage The actual time of supply is far less than the design value, the reason for this phenomenon, in most cases is not the initial configuration, the Panasonic Nv-ds3 Battery reserve capacity is not enough, but the capacity of the Nikon Coolpix s6 Battery did not play out. Reduce the actual battery capacity caused by many reasons, there are Jvc Gr-ax200 Battery quality problems, but more of a use and maintenance issues.
(1) battery capacity
Lead-acid SAMSUNG WB500 Charger battery plates during the manufacturing process, the students charge into the plate, then the positive plate of lead into lead dioxide, the negative plate spongy lead into lead, but the manufacturers into the plate to time is limited, not all of the substances are converted into active substances, for which the new national standard of 90% Motorola HT800 battery capacity as qualified, and only in the subsequent daily use, the capacity gradually to normal, two years after the installation requirements up to 100%.
The rated capacity of the battery pack is under the required discharge rate obtained,
Discharge rate (1 / H) = discharge current (A) / rated capacity (Ah)
For example, UPS power supply used in the typical size of a small Toshiba pa3420u-1brs Battery is l2V, 6Ah/2Ohv, this specification is defined as the output DC voltage l2V, nominal capacity of 6Ah, discharge rate conditions for 20hr. Specific meaning is: the output DC voltage l2V to 20H battery pack placed under conditions of constant discharge rate of discharge, the output voltage has been put down by the l2V l0.5V when measured by the total number of hours should be 6Ah security .
China, Japan, Germany, industrial Sony DCR-DVD91E Charger battery with 10 hour rate (expressed as C10), the U.S. battery industry standard 8-hour rate (expressed as C8,). In actual use, the discharge rate is not equal to the standard provisions of the capacity of the discharge rate, when the actual discharge rate is greater than the nominal capacity specified discharge rate, the actual output capacity of less than nominal capacity.
China's electric power, telecommunications standards, 10-hour rate NEC VERSA FM320 Adapter battery discharge when using the 1 hour rate, its capacity is 55% of nominal capacity, ie 0.55C10. Japanese Industrial Standard specifies 2V/10 hour rate battery, 1 hour rate capacity of 0.65C10, 6V, 12V, 10 hour rate battery, 1 hour rate capacity of 0.6C10. 20 hour rate Panasonic Lumix Dmc-fz3 Battery, 10-hour rate capacity of 0.93C20, 1 hour rate capacity of 0.56C20.
Battery life, there are two expressions: one for the deep cycle batteries used, and the other to float using the "standby power" battery. Deep cycle IBM 40Y7667 Adapter batteries for deep cycle use to indicate the number of its life, the depth to 0.8C10 use of battery charge-discharge cycle, the life expectancy of more than 1200 times, and the use of floating battery life of up to 10 to 20 years. Only 80% of battery capacity that the end of life.
Actual service life and design life are very different, depending on the loss of water in the NEC VERSA FM320 Laptop AC Adapter battery case. Under the conditions used in the design can meet the design life, and when the external conditions such as temperature, charging voltage, depth of discharge exceeds the design requirements and other changes, the actual life will be significantly lower than the design life, the actual use of capacity will be less than design capacity.
(2) The discharge rate of the battery capacity of the actual output
Battery capacity C (Ah) is equal to the discharge current (A) and the Panasonic Lumix Dmc-fz3 Battery voltage reaches the lower limit of the discharge time (h) of the product, and discharge rate (1 / h) is the actual discharge current (A) and the nominal Olympus Li-40b Battery capacity (Ah) the ratio.
The actual operation of the UPS, mains power failure, the inverter requires the battery to bear the full load power, the discharge rate depending on the different back-up time are very different, for example, standard machine 1Omin about maintaining a very short time, the discharge rate large, time-lapse machine up to 4h or 8h, discharge rate is very small. Therefore, the actual Canon Bp-511 Battery discharge rate is not defined in the specification of the battery discharge rate, discharge curve shown in Figure 5-1 reflects the different rates of discharge capacity of the battery.
Tuen smaller pool of actual discharge current, battery voltage to maintain the stability of the longer, and vice versa. For example, 1OOHR battery, when the discharge current of 5A, the discharge rate 0.O5C, the output voltage is maintained at 12V or more of the time up to 10h, when the Sony HDR-SR10/E Charger battery voltage drops to 10.5V when the threshold voltage, discharge time up 2Oh, battery capacity is essentially the release of its nominal capacity. If the discharge current increases to 1OOA, the discharge rate of 1C, the output voltage is maintained at less than more than l2V 1Omin. When the Acer Aspire 7730 Battery voltage drops to the threshold voltage, the discharge can be maintained for longer than 3Omin, the actual capacity of 58.3.M released, far lower than the nominal capacity 1OOAh.
Battery pack to allow the discharge threshold voltage value and the actual availability of capacity (AM all bow the size of the Motorola GP320 battery discharge current are closely related.
Battery discharge time allowed in the actual discharge the battery discharge current, the battery voltage from the rated value down to its threshold voltage to allow the time spent.
The efficiency of batteries available for it in the actual discharge current can release the actual maximum capacity and the ratio of its rated capacity.
Note the different discharge rate case, the dell Inspiron 1545 Laptop AC Adapter battery terminal voltage drop is changing the critical value, the discharge rate is low, such as 0.01C, the actual release of the nominal capacity of close to capacity, which allows the battery terminal voltage drop is high ( 10.5V), the discharge rate is high time such as 1C, the actual release of the capacity is small, but allows the OLYMPUS EVOLT E-410 battery terminal voltage can be lower (8V).
Excessively high current discharge is detrimental to work. Configuration for UPS batteries, the UPS battery alone inverter output current required during the time and battery-powered configuration with a nominal capacity of the battery is not enough, it must be based on inverter when the Camcorder Battery SONY ALL M SERIES discharge rate and the selected Battery output characteristics, and increase the battery capacity with.

Complete two AA batteries/USB power management device
For the consumer handheld devices, the historic two AA (alkaline or Ni-MH battery) power is the most commonly used Panasonic Nv-gs11 Battery solutions, especially in the GPS navigation devices, digital cameras and MP3 players. AA batteries easy to buy, low cost and high power density. In these portable devices, many have adopted the plug-in AC adapter, and provides a USB bus (for data transfer) as a supplement battery power. USB bus power can also be used. The question is how these three different power supply (two AA batteries, AC adapter and USB) to seamlessly switch between. LTC3456 is a suitable solution.
LTC3456 is a complete system power supply IC, AC adapter can be achieved, USB and two AA Dell Lite-On PA-1131-02D Adapter batteries power flux between the seamless management and comply with USB power standards, all of these functions are integrated in a 4mm x 4mm QFN within the package (Figure 1). The device generates two separate power rails: a 3.3V (fixed) main power supply and a 1.8V (adjustable) core power supply. In addition, LTC3456 also includes a fully functional USB power manager, used to store a hot plug power supply (Hot Swap) output and is suitable for low-battery comparator or LDO controller gain independent parts. The device also generates an always-running VMAX output, the output is suitable for such real-time clock for the shutdown period also necessary even in the working state of the key components in power transmission.
LTC3456 contains four high efficiency up to 92% of the 1MHz fixed-frequency switching regulators. Figure 2 shows a typical LTC3456 application. Used in portable applications, most processors require dual-supply voltage. The voltage can be 3.3V (for I / O circuits) and 1.5V or 1.8V (for the processor core). In addition, the processor may also require the power to start in a specific order to prevent blocking or error processor start. Typically, the core power to the I / O power supply before the rise.
Figure 2 is based LTC3456 complete power solutions, including a 1.8V output (for the processor core), a 3.3V output (for I / O), a hot-plug power supply 3.3V (used to store plug-in) and a VMAX output (for RTC)
LTC3456 has a main output for the kernel and built-in power sequencing function. On power, VINT output (a fixed 3.3V power supply) on the implementation of the first power-on operation. It is responsible for most of the internal circuitry. Response to the external load on the output size is limited. Adjustable from 0.8V to 1.8V core output then increased, followed by VMAIN output. VMAIN output (a fixed 3.3V power supply) into the regulation state in the kernel output after delay 0.8ms (typical) power. VMAIN output by the VINT output through an internal 0.4Ω (typ) PMOS switch and produce, and can be used to I / O circuitry. 0.8ms delay processor power in the external circuit to complete the system clock on the stability and load internal registers provide a sufficient time.
LTC3456 generates an adjustable 0.8V to 1.8V core output, the output for the new low-voltage processors (ARM, etc.) power supply. LTC3456 output control circuit allows the kernel to work 100% duty cycle. When the kernel output from the ACER TravelMate 527 Laptop AC Adapter batteries to power, it provides low dropout operation, extending battery life. When the battery-powered, the main converter and core converters offer a burst mode operation (MODE pin can be used to select), so in light load conditions to achieve high efficiency. In the case of battery-powered, the kernel has more than 92% converter efficiency. When the USB / wall power supply to power, the Burst Mode operation is disabled. When powered from the USB to the main converter up to 90% efficiency.
LTC3456 suitable for flash memory card with a built-in hot swap power supply output. The hot-plug output with short circuit and reverse voltage isolation. It allows plug-in system stored on the hot plug. It has a suitable power supply to the flash memory card, 120mA (typical) Built-in current limit.
LTC3456 provides the core for the main output and output short circuit protection. It also provides all of the output (VMAX output excluded) provides output disconnect. In shutdown mode, the core output, main output, and outputs are discharged to ground hot. In VBATT, VINT, VEXT and USB voltage, VMAX output is the highest. The output can be used to provide the maximum output current of 1mA. Even if the IC is in shutdown mode in the case, VMAX output will remain running, and thus suitable for real-time clock to the critical system components such as power supply.
Table 1 LTC3456 PowerPath summary of the work patterns and characteristics
PowerPath control
LTC3456 includes a proprietary PowerPath control circuitry to achieve seamless handover between system power (from two AA NOKIA 9210 PDA battery to USB / wall power, or vice versa). Figure 3 shows a simplified block diagram of an internal power supply path. AC adapter and the USB bus through the VEXT pin to the switching regulator power supply. LTC3456 includes a full-featured USB Power Manager to take advantage of USBHP and SUSPEND pin to control the state of the power flux from the USB pin. USB pin current is flowing through the precise limit of 100mA or 500mA (depending USBHP pin on the state). By SUSPEND pin pulled high to disable all USB functions.
When must raise two AA Panasonic Lumix Dmc-fx30 Battery voltage (1.8 V to 3.2 V) to generate 3.3 V output, and USB/the wall must be the power (4 V to 5.5 V) to produce the same antihypertensive operation voltage, DC-DC changeover will be a particularly challenging job. LTC3456 through the BOOST and BUCK2 converter finished this task. This is a generated 3.3 V power rail the most efficient way. When the battery or USB/communication from adapter to generate 3.3 V output, LTC3456 realizes the higher than 90% efficiency. The kernel output (1.8 V) is through the BUCK1 (by USB/the wall power to power supply) and BUCK3 (by the Canon Eos-300d Battery to power supply) converter to generate. The unique LTC3456 topological structure of a single inductor available to generate 1.8 V power rail, which saves the cost and space. When from the battery to generate 1.8 V output, it achieved more than 92% efficiency. Table 1 LTC3456 lists the different work model.
Portable devices need to realize from battery power to USB or the wall seamless switching power supply (and vice versa) to ensure the smooth operation of the system. For example, a user is a USB cable to connect the portable MP3 music played on board. If the USB cable is suddenly pulled off from the equipment, the user should be able to continue to listen to music, and won't aware of any interruption phenomenon. LTC3456 through the realization of switching power supply system and make the desire of seamless become possible. When SUSPEND pin was low electricity from PingLa to high electricity at ordinary times, not with USB power supply. The main output and the kernel when switching output in both showed less than? % of total deviation, and thus realizes the processor core and periphery circuit to the seamless switch.

It is responsible for most of the internal circuitry. Response to the external load on the output size is limited. Adjustable from 0.8V to 1.8V core output then increased, followed by VMAIN output. VMAIN output (a fixed 3.3V power supply) into the regulation state in the kernel output after delay 0.8ms (typical) power. VMAIN output by the VINT output through an internal 0.4Ω (typ) PMOS switch and produce, and can be used to I / O circuitry. 0.8ms delay processor power in the external circuit to complete the system clock on the stability and load internal registers provide a sufficient time.
LTC3456 generates an adjustable 0.8V to 1.8V core output, the output for the new low-voltage processors (ARM, etc.) power supply. LTC3456 output control circuit allows the kernel to work 100% duty cycle. When the kernel output from the ACER TravelMate 527 Laptop AC Adapter batteries to power, it provides low dropout operation, extending battery life. When the battery-powered, the main converter and core converters offer a burst mode operation (MODE pin can be used to select), so in light load conditions to achieve high efficiency. In the case of battery-powered, the kernel has more than 92% converter efficiency. When the USB / wall power supply to power, the Burst Mode operation is disabled. When powered from the USB to the main converter up to 90% efficiency.
LTC3456 suitable for flash memory card with a built-in hot swap power supply output. The hot-plug output with short circuit and reverse voltage isolation. It allows plug-in system stored on the hot plug. It has a suitable power supply to the flash memory card, 120mA (typical) Built-in current limit.
LTC3456 provides the core for the main output and output short circuit protection. It also provides all of the output (VMAX output excluded) provides output disconnect. In shutdown mode, the core output, main output, and outputs are discharged to ground hot. In VBATT, VINT, VEXT and USB voltage, VMAX output is the highest. The output can be used to provide the maximum output current of 1mA. Even if the IC is in shutdown mode in the case, VMAX output will remain running, and thus suitable for real-time clock to the critical system components such as power supply.
Table 1 LTC3456 PowerPath summary of the work patterns and characteristics
PowerPath control
LTC3456 includes a proprietary PowerPath control circuitry to achieve seamless handover between system power (from two AA NOKIA 9210 PDA battery to USB / wall power, or vice versa). Figure 3 shows a simplified block diagram of an internal power supply path. AC adapter and the USB bus through the VEXT pin to the switching regulator power supply. LTC3456 includes a full-featured USB Power Manager to take advantage of USBHP and SUSPEND pin to control the state of the power flux from the USB pin. USB pin current is flowing through the precise limit of 100mA or 500mA (depending USBHP pin on the state). By SUSPEND pin pulled high to disable all USB functions.
When must raise two AA Panasonic Lumix Dmc-fx30 Battery voltage (1.8 V to 3.2 V) to generate 3.3 V output, and USB/the wall must be the power (4 V to 5.5 V) to produce the same antihypertensive operation voltage, DC-DC changeover will be a particularly challenging job. LTC3456 through the BOOST and BUCK2 converter finished this task. This is a generated 3.3 V power rail the most efficient way. When the battery or USB/communication from adapter to generate 3.3 V output, LTC3456 realizes the higher than 90% efficiency. The kernel output (1.8 V) is through the BUCK1 (by USB/the wall power to power supply) and BUCK3 (by the Canon Eos-300d Battery to power supply) converter to generate. The unique LTC3456 topological structure of a single inductor available to generate 1.8 V power rail, which saves the cost and space. When from the battery to generate 1.8 V output, it achieved more than 92% efficiency. Table 1 LTC3456 lists the different work model.
Portable devices need to realize from battery power to USB or the wall seamless switching power supply (and vice versa) to ensure the smooth operation of the system. For example, a user is a USB cable to connect the portable MP3 music played on board. If the USB cable is suddenly pulled off from the equipment, the user should be able to continue to listen to music, and won't aware of any interruption phenomenon. LTC3456 through the realization of switching power supply system and make the desire of seamless become possible. When SUSPEND pin was low electricity from PingLa to high electricity at ordinary times, not with USB power supply. The main output and the kernel when switching output in both showed less than? % of total deviation, and thus realizes the processor core and periphery circuit to the seamless switch.

Extending laptop battery life Seventeen method
1 Regular defragmentation
Defragging the hard drive that allows you to work faster on a regular basis to maintain efficient disk defragmentation allows the state, of course, when using the external power supply to collate the best. The corresponding speed disk working time is short, it will certainly reduce the power consumption to extend notebook battery life.
(2) reduce the screen brightness
Most of the computer screen brightness can be adjusted, and some may even reduce the CPU frequency. When using the battery for toshiba satellite pro a60 to reduce these parameters can be more effective to extend the battery SONY VAIO VGN-FZ440E life.
3 Close background programs
There are programs running in the background, although not directly see these programs running, but all in the consumption of the CPU processing power, of course, consume battery for dell xps m1330 power. The best way is to turn off all unnecessary background programs, in order to prolong battery life.
4 Reduction of peripheral
USB devices (including your mouse), Wi-Fi wireless connections are able to consume battery power, when the equipment is not in use, the best pull down or masked. Some devices, such as the iPod when connected with the computer will start charging, which use battery-powered notebook, he may be careful not to do it.
5 to add more memory
More memory means that notebooks do not be so dependent on virtual memory. Virtual memory is built on the hard drive above, obviously access memory power consumption is lower, so more memory rather than hard to read, to reduce power consumption. However, increasing the energy consumption of memory can trigger the same problem, so that the computer is often called the virtual memory of friends, most the time to consider adding memory.
6 CD-ROM with a little less
Although the hard drive power consumption is relatively large, but in fact drive more in the eyes of the energy consumption. Even when not in use when the drive is still the same rotation, the energy consumption. If you can find a suitable virtual CD files through a virtual drive to read, obviously much less power.
7 Keep feet clean touch
Here suggest that, look at the dell inspiron 6000 laptop battery every few months to clean the metal contact pins can be a cloth moistened with alcohol wipe. This ensures that the battery inside the toshiba dynabook satellite ss 3500 series charger battery, can be more effectively transmitted to the various components to consumption.
8 take good care of the battery
Take good care not let you put the battery shelf, but regular exercise about it. Do not let the latitude c640 battery fully charged, "doing nothing" in a long time to be Shang Hao. Once fully charged, you should at least once every two or three weeks fully used once. Of course, do not let your battery completely consume the electricity, it is to deal with the old toshiba satellite p105-s6024 battery memory effect in it. . E
9 dormant rather than standby
Although the standby allows users to immediately return to work status, but this feature is obviously better than sleep to save power. Sleep under the same ability to save your current work status, and almost able to completely stop the consumption of electricity for laptops.
10 lower working temperature
Reduce some of the notebook temperature to more efficient operation. Notebook with a long time, will accumulate a considerable degree of internal dust, which can make the work within the notebook temperature. Regular internal cleaning notebook for extended dell inspiron 15r battery life is also very important.
11 optimized power options
In the Windows control panel, power options, there is a button, this button can be set to optimize your laptop's power supply options. There are some more powerful notebook comes with power management software, it is more user-friendly to use.
12 non-multi-tasking
The best time to use the Sony pcga-bp2nx battery only for a task, rather than changing with reports, send and receive mail while in the background, while playing music, etc. ... ... multi-tasking, so you can only consume the battery faster, and may which no work done no electricity.
13 small run large programs
Extend battery for acer aspire one 10.1 life, the best little big run heavy program assignments. E-mail, electronic document processing, it is clear than, play games, play DVD discs more than a small power consumption.
14 replacement of the books
To accompany their books for several years is certainly not willing to throw away, but the harsh truth is: they have been old, has not keep up the efficiency. Latest laptop, energy consumption in the office side has a lot of upgrade, you want a longer pa3285u-1brs battery life, it may be picked up throwing old love new love.
15 to prevent the memory effect
If your laptop's old, it must pay attention to prevent "memory effect" generation. Each twenty-three weeks let your battery is fully charge / discharge time, of course, if you use lithium-ion toshiba dynabook ss 3410 charger battery, then do not have this trouble.
16 turn off auto-save
Microsoft Word, Excel and other programs have auto-save feature, in most cases this is an intimate setting, but the use of laptop batteries, which adds to the hard work. Turn off this feature, you need to remember always to save the document, the last province of the results of hard work down the drain.
17 Reducing the graphics application
For example, we can change the graphics resolution, while closing some open for aesthetic effects, the graphics card is a noteworthy, because the graphics card and hard drive power consumption has been almost, some even higher.

Battery using the common problems and solutions
Battery using the common problems and solutions (a)
Laptop batteries in the course of some of the problems often occur, and some problems of their own books and use little effect, but some problems let us compare headache friends.
One problem: the battery installed repeated several times, still can not boot
Cause: 1 battery is not installed correctly 2. Battery is 3 acer aspire 1300 series battery idle for too long 4 the depth of discharge treatment did 5 other reasons
Solution:
1 double-check the power connector and battery connector link is correct.
(2) Replace the battery, use the adapter to activate the batteries in, in no case do not unplug the power adapter, re-boot.
3 Check the battery power often, do not idle too long.
4 Replace a new Sony pcga-bp71 battery.
5 Try to press the power button to boot.
Notebook lithium batteries
Second problem: the battery is idle for too long, again, use less power or no power of
Cause: 1 before the power is not idle more than 2 storage FUJITSU stylistic st5010 battery quality issues or environmental problems, the battery case of natural wear and tear 3 idle for too long, there is no right to charge and discharge operations
Solution:
1 If the user wants to store the battery before storing it in the battery charge to 50% of electricity storage.
(2) try to put some of the storage battery when the relatively dry areas, the temperature about 20 degrees most appropriate.
3 after the emergence of the phenomenon of self-harm can also be used normally to full power.
4 If you do not trust, then please replace a new Sony vaio vgn-fz51b battery.
Question three: the battery shows fully charged, unplug the adapter, but not after the normal power supply, leading to crashes
Cause: 1. Working environment temperature is too high, causing the battery into the self-protection program (2) Sony vgp-bps3 battery charging problems, resulting in distortion power display
Solution:
1 shut down the computer, remove the battery to the battery cooling to normal temperature used in the normal working environment, because the self-protection program can be self-healing.
(2) replacing an original Acer aspire one 10.1 battery in the same environment, check whether the same problems, if there is no similar problems, then please contact the service user point, check the machine is faulty.
3 the right to keep and use the battery, so as to avoid distortion.
Maintenance of the right laptop battery
Laptop battery quality and battery life is when you buy laptop special care, in fact, how to make good use of laptop battery, how to extend its use and application of work life issues, troubled by the majority of laptop users is undoubtedly a problem, laptop battery the use of a variety of methods and techniques, which usually requires the use of more in learning and application. The next comparison would introduce three simple maintenance methods. We want to help.
Oh, I have power
1 First, the user wants to make the books of the Dell inspiron 6400 battery longevity, it would need to have a good start, when we buy laptop, the battery should be some charge left, this way, the user experience when using the machine (if the users find the battery battery is full, then the proof of this machine was used), this time, you should not use an external power supply, the battery inside the power exhausted, until the shutdown, then use the external power supply charge.
2 Do not charge the battery in the rain: rainy days are often thunder and lightning caused by the current moment in terms of impact on the battery is extremely unfavorable. In addition, the process of notebook Dell inspiron 2500 series battery voltage stability is particularly important. Users should avoid the notebook's power adapter and power electrical appliances (such as air conditioners, refrigerators, washing machines) connected to the same outlet.
Avoid high-pressure and high temperature
3 regular battery maintenance: If you can not guarantee every time a thorough clean and recharge the battery used, then at least once a month for a standard charge and discharge (ie, clean and re-filled after the release of full), or regular use BIOS battery calibration feature built-in maintenance, so that Dell inspiron 11z battery life is very good.
Oh, the storage battery to use a clean
4 If some users do not use a long battery, you need to charge a battery to power more than 50% during storage, it is a good follow-up to use the Acer aspire 3000 battery. In addition, the storage process must pay attention to room temperature, the temperature is too high or too low impact on the battery is relatively large, the best storage temperature is 20 degrees.
How to correctly identify the battery
If the laptop with the desktop than the biggest advantage is mobility is good, then we have to mention a key component, because there is no part of this notebook does not have the mobility, almost equal to a scrap metal, then this component what is it? Presumably many of my friends have guessed, it is the Dell vostro 1400 battery.
Detailed map dismantling the battery
Now comes the battery, then the user in the purchase of books to choose one when the battery is good or bad will be inevitable matter, and the most intuitive way is to look at the battery cell capacity. Currently on the market for notebook computers because, according to the different size and performance, so with different types of batteries, which are mainstream books with 6-cell Dell inspiron 1521 battery, while the large size of most books with a 8-pin or 9-pin battery, small size and thin with the general core is 3 or 4 cell battery.
There are also a number of friends a better understanding of the laptop when in the selection of products will be more focused on the battery "mAh" unit size, "mAh" unit is battery capacity, and its Chinese name is ma. Purchase in general, many of my friends might think that a large mAh battery unit will have a longer life time, but the reality is not the case, we can often be seen on the sony laptop battery "6-cell 4400mAh", "4-cell 2200mAh "nominal value such as batteries, over time we believe that directly determines the capacity of 4400mAh or 2200mAh laptop working hours. But in fact the real master, a unit of battery capacity should be considered "Wh", its Chinese name "Wh." Of course, "Wh" and the "mAh" is closely related to the following formula: Wh trout × 1000 = mAh. We will also see the battery "11.1V 4400mAh 48.84Wh" such numbers, then these digital how a relationship it is very simple, we only need 11.1V × 4400mAh = 48.84wh.
In addition, I also mentioned before the current market of several commonly used battery, then how come we have to verify its accuracy it, one is the professional approach, we need to know the Dell latitude d610 series battery voltage and capacity of the battery in the end can know is a few core friends. The other is the laptop this way, we only need an approximate 5 batteries weigh, you can estimate how much the core of the.
Method of calculating the number of battery cells:
Battery voltage: voltage value 3.6 or 3.7 = n1
Batteries Capacity: Capacity Value 2200,2300,2400,2600 = n2
The total number of battery cells: n = n1 * n2
For example: If a voltage is 11.1V, 4400mAh battery capacity, the number of batteries is: n1 = 11.1/3.7 = 3 n2 = 4400/2200 = 2 the total number of the battery core is: N = n1 * n2 = 3 * 2 is the 6-cell.
I believe that, by the above two examples the user can rest assured that the selection of sony vaio vgn-fz285u battery and also to prevent the flicker of the scene again, we only need to remember that these two formulas, we can easily solve the problem of selection of battery friends.
How to buy laptop battery
Current notebook accessories market can be described as complex, in particular, that a acer laptop battery, original fake, renovation of old batteries, not the make addresses, and so the warranty has become an empty word problem after another. So how do we buy laptop batteries?
First thing to say is the battery warranty, the battery market, we see that there are many, the warranty period can be divided into several, such as 3 months ah, six months, ah, ah, and so a year. We say that the one-year product warranty is a Class A material, a wealth of experience in laptop battery R & D, quality control and process improvement, this battery are generally genuine original. And almost three months or six months the product has one thing in common, that is, neither the manufacturer, address, telephone number, neither the protection of the content, nor the scope of protection, such as removal of waste Dell inspiron 9400 battery are mostly electric battery recycling core and the protection board, and even some not even protect the board did not, the cost is very low, very dangerous to use, consumer rights can not be guaranteed.
Secondly, try not to say that users buy compatible battery, compatible battery although cheap, and soon you can get, but there are also dangers, such as compatibility, quality, too, but off the battery and so on. So I suggest you buy the original battery, quality guaranteed, although the price is too high, but rest assured that even after the user bought ah, if some users do not want to buy original Sony vaio vgn-nw21ef/s battery , it would buy the adapter or UPS uninterruptible power supply it.
Broadcast to Tencent microblogging
Jingdong purchase page
Finally, I want to say is, for those who need a friend to buy Dell vostro 1700 battery, you'd better go to the official designated service point, or to find out if there is Jingdong online match with their own batteries.

Battery voltage: voltage value 3.6 or 3.7 = n1
Batteries Capacity: Capacity Value 2200,2300,2400,2600 = n2
The total number of battery cells: n = n1 * n2
For example: If a voltage is 11.1V, 4400mAh battery capacity, the number of batteries is: n1 = 11.1/3.7 = 3 n2 = 4400/2200 = 2 the total number of the battery core is: N = n1 * n2 = 3 * 2 is the 6-cell.
I believe that, by the above two examples the user can rest assured that the selection of sony vaio vgn-fz285u battery and also to prevent the flicker of the scene again, we only need to remember that these two formulas, we can easily solve the problem of selection of battery friends.
How to buy laptop battery
Current notebook accessories market can be described as complex, in particular, that a acer laptop battery, original fake, renovation of old batteries, not the make addresses, and so the warranty has become an empty word problem after another. So how do we buy laptop batteries?
First thing to say is the battery warranty, the battery market, we see that there are many, the warranty period can be divided into several, such as 3 months ah, six months, ah, ah, and so a year. We say that the one-year product warranty is a Class A material, a wealth of experience in laptop battery R & D, quality control and process improvement, this battery are generally genuine original. And almost three months or six months the product has one thing in common, that is, neither the manufacturer, address, telephone number, neither the protection of the content, nor the scope of protection, such as removal of waste Dell inspiron 9400 battery are mostly electric battery recycling core and the protection board, and even some not even protect the board did not, the cost is very low, very dangerous to use, consumer rights can not be guaranteed.
Secondly, try not to say that users buy compatible battery, compatible battery although cheap, and soon you can get, but there are also dangers, such as compatibility, quality, too, but off the battery and so on. So I suggest you buy the original battery, quality guaranteed, although the price is too high, but rest assured that even after the user bought ah, if some users do not want to buy original Sony vaio vgn-nw21ef/s battery , it would buy the adapter or UPS uninterruptible power supply it.

HP EliteBook 8560p Laptop Battery Use Manual :
New HP EliteBook 8560p Laptop Battery needs charging and discharging cycle first before the regular usage. Because laptop battery from factory to the users' hands that exists the time differences, and the electrode materials will be its passivation for the battery of the longer time difference, which is why the purchase of new batteries need to be completely filled with charging and discharging cycle three times to eliminate electrode materials passivation, to activate HP Compaq Business Notebook 6510b Battery performance, to reach maximum capacity. Meanwhile, the laptop has the data transmission agreement end between battery and the computer, after the need of two or three times charged and discharged cycle, the percent of its real capacity can keep pace with the percent of content on the computer's screen. Cycle's steps: insert incomputer to discharge until the shutdown, and then recharge the notebook battery, charging time must be over 12 hours, to repeat the action of charging and discharging for three times.
The proper use of HP Compaq Business Notebook 6515b Battery usually will be very crucial. Discharge can not fully take end, there are about 5 percent of electricity charging, we should not be spent replenishment. Otherwise, it will accelerate the aging batteries scrapped. If the relatively high capacity (such as more than 80 percent) under the charge of the case, will accelerate the aging of the HP EliteBook 8560p battery. Use lithium ion batteries in 25 to 35 degrees centigrade, will show better performance. The low temperature or high temperature than the above state, its performance will be greatly devalued.
When using the HP Compaq Business Notebook 6910p Battery replacement, fever is a normal phenomenon, because in the process of the battery charged and discharged, energy conversion will result in heat and at the same time the amount of heat will be transmitted to the battery. But if overheated (burning), stop using it immediately and ask for the professinonals to check.
When not using HP Compaq Business Notebook 6735s laptop Battery, charge it to about 50 percent's energy and take out of it from equipment and stored in temperature :10-20 degrees centigrade, humidity :45-75 percent. Do this each day and more than one charge, and discharge cycles to eliminate passivation of electrode materials, and activate battery performance.
Prevent the liquid entering into the latop pc battery. Once liquid immersing into batteries, stop using it, dry with a dry cloth and put it in the ventilation to dry, otherwise they will result in danger.
Not arbitrarily demolish the laptop battery. In order to prevent short circuit, do not use metal objects (such as necklaces, etc.) batteries hit the positive and a negative extreme.
Don't let the HP EliteBook 8560p battery replacement near the fire source, not subject to any pressure, otherwise they will lead to danger.
If the notebook computer battery charged and discharged after three complete cycle, performance or significance still decline indicate that you should change the battery.
