Do RV Batteries Freeze in the Winter?

[Big_C]

We purchased four 6volt AGM Lifeline GPL-4CT batteries last fall. For twenty years we have driven down to Mexico for the winter. As Canadians we will have to stay home because of the Canada/US border likely remaining closed for a few more months. We have no idea what to do with our batteries. No one is saying that they won't freeze, they might not or they might not.

Here in our area of B.C. it can get down to -30C/-22F for one - two weeks maximum and some years not so cold. We are forecast to have a colder winter this year. What have any of you done here in Canada or the northern US done with your sealed batteries? Should we take them out or leave them in?

Charged batteries will not freeze. Low or dead batteries will freeze. Unless you can gurantee that the batteries will stay fully charged, I would pull them and install a trickle charger if not inside a heated area. Doug
