Hi
I have an old 2007 Macbook with a dead battery. Mac OS detects the battery but cannot charge it and dispays a message: replace battery.
This is a 6 cell battery with 3 blocks of cells connected in series and each block contains 2 cells connected in parallel.
In order to try to avoid buing another battery, I've desoldered all the cells and check the voltage of each one of them, which ranged from 0.8V to 1.2V.
So I've charged them individually and all of them are at 3.7V, now.
After a couple of days they still hold the charge.
My problem is that I didn't know about the BMS sensing mechanism via a thick piece of metal and I've just cut the piece of metal and desoldered the cells one by one. Now, I don't know how to connect the sensing wires back.
Can somebody help me please? Is it ok to replace that strip of metal by wires?
Thanks in advance.
Best regards,
Pedro
