Hello,I am a seasonal camper, is it good idea to unhook the battery during winter, we still have electricity coming to the camper but just wondering if I bring the battery home during the winter months and charge it every month at home till spring? Thank you, Ron.

If you keep your battery fully charged it won’t freeze and it could stay in your RV.

Disconnect and leave it in its compartment. Check water when hooking it up.

Ron, Without knowing what the converter is, this question cannot get an accurate answer. While disconnecting is safe in the short term, the bank will still self-discharge at some rate that is greater for older jars. No matter how short you expect your absence to be, it can happen that it is longer. I one time did a full winterize of a client's boat and was not called back to put it back in service for three years. Matt

Would be nice to know what type of battery, too. Make model age? Some types of battery self discharge more slowly than others when just disconnected and left in place. If it's a wet cell type, you should try to keep it charged in the very cold temps of winter. AGMs a little less so, and Lithiums even less than that. If it's not inconvenient, bringing it indoors over winter works, too.

Wet cell batteries full charged with no load are fine in the cold all winter. Been doing that for 40+ years with the batteries in my boat. In Ont Canada it does get cold. Never had a problem. They discharge very little in cold weather.
