I’m a new owner of a beautiful 32-foot Winnebago Access, and I just removed my chassis and deep cycle batteries when I put the RV into storage for the winter. Does anyone have any recommendations ...
The only time I had a battery freeze on me was when a cheap Harbor Freight maintainer shorted and the battery went dead.
Make sure that water levels are topped off. Fully charge batteries completely then disconnect the negative cable to make sure there is no possibility of current drain. Assuming that your batteries are in good shape they will be okay until spring.
