many lithium battery pack failure is the result of a failure of energy-saving core

Method of repair laptop battery (A) causes damage to the battery HP Laptop Battery IBM Laptop Battery Notebook computer battery a long time, I am often dissatisfied with electricity charge, and even the battery is damaged, the specific performance is larger resistance, the voltage across the charging up faster. This easy to charge control circuit judge to have full capacity will naturally decline. As the larger battery internal resistance, discharge voltage drop, high speed, so the system is easy to mistakenly believe that voltage is not enough power is low. Comparison of the discovery of short battery life, should take corresponding measures. (B) of the battery refresh program to restore the battery's 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 distribution for the nickel-metal hydride battery (Ni-Mh) batteries, as usual discharge properly, leading to the battery discharge time is short, only less than 5 minutes, if carrying a laptop to work, then it is very inconvenient, what methods can restore the battery's discharge time? In response to these circumstances, we can use the IBM has launched a battery refresh program to refresh the batteries, discharge time to recovery, specific methods are as follows . (1) the use of AC power to the laptop, the first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download the IBM provided 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 just download the file, the implementation of the battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, and then press the Enter key to the implementation of the self-extracting operation. (4) boot floppy disk with this computer, the screen appears StartingPC-DOS. . . Message. (5) prompted unplug the AC power, the program will automatically be on the Ni-Mh battery discharge, discharge is completed, the system will automatically shut down. (6) The battery temperature is high at this time, should not immediately start, after the battery cool for a while, plug the AC power (7) boot the computer with a floppy disk, the Autoexec. bat file will automatically run the refresh program, and ask the user whether to proceed. Select yes, press the Enter key. (8) At this point, refresh process began to refresh the battery, the process soon, when the return to DOS prompt A:> when that refresh is complete. (9) Shut down the computer, and charge the battery until the light turns green so far. (10) The above procedure is repeated three times to get the best results. In addition, many lithium 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 completely consistent with the nature, quality and use for a long time some little worse after the beginning of aging, and damaged the whole (in series) if the discharge curve. Interest and ability of the reader can try to open the battery pack, the multimeter's help, you can quickly find the damaged batteries (abnormal voltage). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product. (C), notebook battery maintenance 1. When no external power supply situation, if the working conditions at the time being less than PCMCIA card slot, it is recommended to remove the card first to extend battery life.    2. Room temperature (20-30 degrees) for the battery the most convenient working temperature, the temperature is too high or too low, the operating environment will reduce battery life. 3. Can provide a stable power supply in an environment using a laptop computer, remove the battery to extend battery life by not correct. On the ASUS laptop, when the full battery charge, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur 4. Proposal to conduct a three-month average battery power correction action.
