Can a frozen battery be saved?

[TCNashville]

Just curious if a frozen battery can be salvaged. Battery is about 2 years old.

Maybe but probably not. Thaw it out, being careful about acid leaking from cracks during the thaw process.

Take it to a battery dealer who will charge it and test it for you. Check around, some may not be able to do it.

Odds are, it is toast.

For your next one, get a battery tender, leave your RV plugged in, bring it indoors for the winter and charge it every few weeks, or some other way to keep it alive for the off season.

Lots of threads on dead or dying batteries, how to keep them alive.

If it's not completely toast, then it will have significantly reduced capacity. RV batteries are undersized to begin with so you will not be happy with the performance of your compromised one if it works at all.

I use battery tenders for all my toys that use batteries. They are a "set it and forget it" kind of thing.

Not worth anything except a core exchange on a new battery.
