Service battery after cold temperatures?
Hi, I have a 2006 macbook with a aftermarket battery that I got off amazon for $20. The battery works perfectly when I leave it in warm temperatures but when I bring the computer outside (even when it is off) it looses its maximum capacity from 5462 mAh to 4021 mAh. Its factory maximum capacity was 5600 mAh.
Also, the macbook shuts off at 25% battery no matter what and it will not turn back on without the magsafe adapter.
Any ideas or explanations?
