I have 820-3476 mildly water damaged, battery have water stains.

The macbook turns on with magsafe plugged in. Original damaged battery says "battery need replacement". So I order replacement and just received. I dont think it is original battery.

Macbook doesnt charge or sense new battery at all.

I already ask question on how to test the battery (answer was cant).

Can I test motherboard some how?
SYS_DETECT_L on battery connector keep going from 0.010v to 0.500v with new battery. SMBUS_BATT has 3v , and PPVBAT_G3H_CONN jumps to 3.5v and then goes down


What can I check to make sure I just have a bad battery or something else?

If it still sees the old battery as needing replacement the "new" battery is probably just garbage. Also check if PPBUS is still at 12.56V and not 12.3V
