Battery ps5 controller

[zis2104]

I have check 1 battery and it doesn't deliver 4.2v, but 2.88, and why doesn't it recharge?

It's either gotten under the lockout voltage or it's bad. Try letting it sit overnight charging in the controller first. If that doesn't work, then take a bench power supply and force 4v in there for a coupe of minutes, keeping an eye on the battery the whole time. Remove the power and check to see if it's over 3.5v. If it is, then toss it in the controller again and let it charge, if it is still under 3v then recycle it and get a new on.

I tried to recharge it for 3 hours, I don't have a bench power supply and I think it's the fault of the previous owner who perhaps charged it with super fast charging
