Ryobi one+ battery won't charge

[squowse]

What can I do with this. When I truly to charge it goes to flashing green and red leds meaning battery fault.

It got wet, opened it up and dried it out, seemed to work at first but it won't charges force more than a minute now.

interestingly the cells measure at between 4.22 and 4.25V each. State of Charge 100% I believe?
maybe I'll try using it and see if it "resets".

EDIT - no no power at all. I presume it's the BMS not working

The next step would be to disassemble it and test both the BMS and each cell individually.

Considering that the current minimum wage is $7.25 per hour, the cost of identifying the failed component(s) and replaceing them would be about the same as buying a new unit.
