Method of laptop battery repair

(A) cause damage to the battery
Laptop battery a long time, I am often dissatisfied with battery charge, and even show the battery is damaged, specific performance is larger resistance in the charging voltage rises faster at both ends. So easy to determine the charge control circuit has been filled, the capacity falls. Since relatively large battery internal resistance, discharge voltage drop, high speed, so the system is not easily mistaken for voltage, low battery. In that relatively short Camcorder Battery SHARP VL-E720  life, should take appropriate measures.
(B) the battery refresh program to restore the battery discharge time
Big brand laptop has a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650 based laptop, the battery with a nickel-metal hydride (Ni-Mh) batteries, as usual charge and discharge properly, causing the battery discharge time is short, only less than 5 minutes, if carrying a laptop to work, then it is very inconvenient, what can restore the battery discharge time?
For the above, we can use the IBM has launched a Canon xm1 Battery refresh program to refresh the battery to discharge recovery time, specifically as follows.
(1) the use of AC power to the notebook computer, download the first provided by IBM TP390/390e/390x series laptop battery refresh program.
(2) Restart your computer, press F8 to enter boot menu, and select safe DOS mode.
(3) into the directory where the file you just downloaded, perform a Panasonic Nv-mx5 Battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, and then press the Enter key to execute the self-extracting operations.
(4) Boot the computer with this floppy disk, the screen StartingPC-DOS. . . Prompt information.
(5) Follow the prompts to unplug the AC power, the program will automatically Ni-Mh battery discharge, the discharge is completed, the system will automatically shut down.
(6) The Canon Digital Ixus 430 Battery temperature is high at this time, should not immediately start, let the battery cool for a while, plug the AC power.
(7) Boot the computer with a floppy disk, the Autoexec. bat file will run automatically refresh program, and asks the user whether to proceed. Select yes and press Enter.
(8) At this point, the program began to refresh the battery refresh, the process soon, when the returns to the DOS prompt A:> when that refresh is complete.
(9) Turn off the computer and charge the battery until the light turns green so far.
(10) The above procedure was repeated three times to get the best results.
In addition, many lithium Acer Aspire 9301awsmi Battery pack failure is the result of a failure of energy-saving core, this phenomenon can not be avoided. Because each cell batteries can not be exactly the same nature, with some slightly lower quality long after the beginning of aging, and destroyed the whole (the series after) the discharge curve. Interest and ability of the reader can try to open the battery pack, with the help of the multimeter, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of replacement Canon Np-e3 batteries can be qualified product.
