I have a ping 48V 20AH battery I purchased over a year ago and have never used it yet...yaaa dumb I know.
But I did put it on the charger every several months.
The first time all the little LEDs lit.
This last time all of them lit up except for three of them.
I measured 57.3v after the charger kicked off.
What voltage should I measure on a fully charged battery?
Do you think I have some bad cells...could they possibly recover after discharge/charge cycles?
