MacBook senses battery but doesn't run off or charge to the battery
I have an Early 2015 Retina MacBook Pro 13 inch. It had water damage. I have cleaned the logic board with an ultrasonic cleaner. Everything is working fine except the battery won't charge and the MacBook won't run off the battery. The MagSafe connector turns amber as expected if it were charging. The MacBook indicates a 91% charged battery and that it's charging but the 91% never changes and the it turns off immediately when the MagSafe connector is disconnected.
This MacBook Pro has the 820-4924A logic board. I have checked the current sensing resistors at R7151, R7152 and R7121, R7122 and they all check out at the proper resistance. (The 0 Ohm R7152 resistor measured as close to 0 ohms as I could test, the other three resistors were within 3%)
I don't see any visible corrosion anywhere.
What other locations should I be checking?
Edit: Thanks Dan for the CoconutBattery suggestion. Thanks Paul for your comment on the battery management logic board. The battery does have a small board that attached directly to the main logic board. I haven't cleaned that board since it's obviously attached to the battery and it's glued in. Here's the CoconutBattery screen shot:
The battery was working fine before the water damage. Is it posible that water damaged the battery itself, or more likely the battery's own logic board? Do you think the main 820-4924A logic board is likely fine?
