Frozen Battery Cells

Better yet, next year don't store them uncharged!

Treat your batteries like a pet.
You wouldn't leave your pets out in the cold, right?

My batteries are outside dogs. :W I can't even imagine lugging those things into my house for storage.

I take oldman's route.

The solar panel keeps our battery charged and we got down to -20

My two 6 volt house batteries froze a few years ago. They were slushy, not frozen solid.
I thawed and recharged them, they came back and worked great.
I was lucky. I now keep them plugged into shore power 24/7/

It depends on the state of charge in the battery.Electrolite will freeze if it does not have the correct specific gravity.

I tried to copy the answer but could not post it.

Do a search ""Will electrolite freeze"" and look at the chart. This should help

Most batteries die of abuse and neglect, just like yours. Consider it a learning experience. Next year keep them charged and they won't freeze.

..

Charge them, check the fluid level, and don't abuse them.

If one is prone to abuse a set of lifelines might be in order, freezing won't damage them, they discharge slower than most, and are sealed so no maintenance is needed.

For the few min's it takes, I pull the battery and store in the house. Never a concern that way. There is really no reason to leave it in the trailer over the long winter months.
