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 ...
I guess everyone thinks different on this forum but if you fully charge your batteries before storage and remove the neg cables, good batteries will last over the winter and not freeze. I fully charge mine in Nov when I winterize and recharge in the spring. There is no need to have a maintenance charger on you batteries unless they have lost a significant amount of capacity.
