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.

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.

I would fully charge it, then equalize, disconnect the negative cable and recharge again in April. A good battery that is fully charged will not freeze over the winter months. Self discharge is also less in cold weather.

^^^^^^
That's all you need to do for the winter. My batteries discharge less than 10% doing it that way for 5-6 months in the winter.

Removing them cant hurt. Trojan says to avoid freezing temps. If you cant avoid freezing temps keep them at a high state of charge. But trojan also says to avoid keeping the batteries at a constant high state of charge.

If the batteries are easy to access and it helps you sleep at night then store them at home. If buying new batteries doesnt break the bank then maybe the effort is not worth it. Would suck to hurt your back trying to remove a battery when the life expectancy wont be significantly increased.

I remove my batteries to save money (hopefully) and helps me sleep at night.
