My experience with frozen batteries has ranges from plates being pushed around and consequently shorting to literally the size of the battery being broken open. The first rule is never try to charge a frozen battery the battery needs to be thawed first before even attempting to charge I have stop trying to revive batteries that are that far gone.

When I inspected the electrolyte levels I discovered it was frozen in some cells, the voltage of the 48 volt pack was ~8 volts, I didn't check individual batteries due to these facts...I'd seen "enough". Recently temps have been in the high teens, though we are back up to low 30's. He does not have a genny or battery charger! I have a DC genny which I could use to charge these batteries but should I waste my time and his money trying to save them? Others' experience with this situation?
