The battery discharges itself after disconnection - voltage 10V

It's enough that the battery fell somewhere and it's linden.

I think my friend is arguing because I didn't come to a conclusion

1/3 is otherwise 33% (up to 35%, therefore only 2 pp).

This would show that it is closer to 35% and not 50%

i.e. between 35 and e.g. 40

Buddy, you are solving a topic that is simple, let him replace the battery and you will see it will be ok.
I'm sure of it.
I don't want to argue with you, we've been through this before.
Say it's a bad idea to borrow another battery to test?
Sometimes we break down that open door, but why?
Do we have to catch up with ambitions, people expect simple and sensible advice, not chasing with meters, maybe you tell him to measure the charging frequency with an oscilloscope.
Boy, have mercy, the battery is not super electronics.
I don't want to offend anyone to the administrator, but I don't like it when someone learns a bit of electronics and considers himself a god, people write here for help, not reading how hopeless they are.
Sometimes I help by writing and as a company I may not do it (I can charge money for it), but you always have to be human.
Such a small quote, let whoever thinks otherwise, cast the first stone
