Do RV Batteries Freeze in the Winter?
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...

I had a cheap Harbor Freight maintainer fail. It shorted and drained my two Trojan 6 volt batteries which froze and busted. For several years I make sure my batteries are fully charged and then disconnect the negative battery cable. Have had no issues here in Minneapolis where temps quite often will hit -20F or colder.
