Got this board. Battery is ok because i take it from another good working mac. When connect to this mac it is not charging and always says "battery must be replaces". Board seems to be clean enough, no water damage.


What can i check?


P.S. On it's original battery i was getting Kernel right after login. After battery change (also tried another one) it see battery but doesnt charge and tell "must be changed".

What macOS does it have?
Did you try its battery with another board?

NLBA1 can help you to diagnose the battery in this case.

Test it installing original macOS; Shift + Command + Option + R to open Internet Recovery.
Save data first, if needed.
