Hello fellow RV friends!
I have a travel trailer and was wondering if I can disconnect my batteries for the winter so that they last longer but still have it plugged into shore power so I can use the heater? Should I turn the converter off too?
Thanks everyone!
Scott

I will say you can. Everything in my TT works on shore power, with the battery unhooked. I wouldn't worry about the converter. I can't turn mine off.

Since most power centers are also a battery charger, I'd just leave the batteries connected. It will not shorten the life of your battery unless there's a problem in the charging circuit of your power center.

YEP^^^^^

If you are going to be plugged into AC power source then leave batteries in place, disconnect on and converter on.....
Converter will supply the DC System AND maintain the batteries with float charge

IF you remove batteries....disconnect off and leave converter on for DC Power....furnace runs on DC


Is it time for your medication or mine?

Yes, assuming your converter is roughly ten years old or less.

Your batteries would be better off if you disconnected them instead of leaving them on a float charge.
The converter will provide enough to run the heater if you need to.

Mine stays plugged in any time it is in storage. And since we always have FHU sites, the only time it is not plugged in is when we are on the highway. 11 years and I have replaced the batteries one time. I do check the water regularly.

Thanks for the input! My rig is only 2 years old. Sounds like half are saying to just leave the batteries connected and the others say to disconnect. It charges it to 13.1 V, and I do regularly check the water levels. So far so good. I want to install a cut off switch, that'd be nice and easy and then I will disconnect them when not in use.
Most importantly, I appreciate knowing I can just leave the converter on so I can use the heat if I want to use it as a man cave this winter.
Thanks!
Scott

Man cave or potential dog house?
