Laptop Battery lifetime HW hack

[Chowchilla]

As far as I know, all the batteries on the market have a special program embedded in their uC blocking the batteries performance after a certain amount of time or cell recharges.

After 2-3 years constant care of your Li-Ion battery, you will surely encounter the phenomenom of dropping its duty cycle from 2 h to NONE (2-3 min) instantly. Well, depends on manufacturers mostly.

Is there a method to bypass this programming? I know that reverse engineering these uCs is difficult (impossible), and you cannot simply repogram the Processing Unit.


Off topic: is this thread considered hack topic? Do you support such threads, admin?:P

Add a couple years, by calibrating the laptop battery.

This battery is about 7 years old.
Calibrating the battery manually

is the part I use.

Immediately check the power level when you start it up. If less than 10% you are good. But if it is over 10%, fully charge the battery and do it again. Should be fine when you check the power on the next time you start to charge it.

Nice Guide! I will try it ASAP. I just need to get rid of the workplace junk.
