I have a few laptops that need new batteries. The fact that OEM is expensive and most of the time you cannot find any good after market I would like to rebuild them. I would also like to rebuild them because battery technology is better now and I think I can get better batteries.
Jump Starting Dead Batteries
One of the problems that I have read about is if the battery side of the battery circuit loses power then the circuit blocks/locks. Recommendations so far seem to be:
Jump start the circuit with voltage[1] Independently charge the battery side[2]
I have also read somewhere that you can never get the circuit to start again so during the repair process keep it powered.
It has been called a control circuit,
Recalibration
- To correctly build a battery pack, you'd have to clear the EEPROM through the SMBUS interface using a software.[3]
