After sitting for about six months, I have a battery that is probably toast.
It's a standard 12V, wet cell battery that is currently reading 6.2 VDC. My charger doesn't indicate that it is bad, but will only charge for 5 minutes or less before the thermal overload shuts it off.
I read between cells, looking for a bad cell and the difference between cells is proportional all the way across.
Any idea what went wrong?
More important - is it fixable or is it trash?
