Do we leave the battery disconnect key in the “on” position? Do we leave the “converter” on? Or should we not use the 110v at all?
Note: We live in southern Tennessee.
Thanks for your help with this. We really appreciate it!

If your converter "floats" the battery at 13.2-13.8V, then you should be good to go. I've had a 5er with a constant voltage 13.8V converter floating a group 24 Interstate Deep Cycle for over a year. It has the white translucent sides that allow you to see the cell acid levels. Hasn't budged.
In addition to floating the battery, the converter is powering a few lights to repel rodents as well as my wifi DSL modem and Blink camera module for remote viewing. I have had zero problems, and I visit every 2-6 weeks. I visually check the battery fluid levels maybe 3 times per year.
HOWEVER, the more conservative approach is to just power everything down, take the battery with you and put it on a battery maintainer in a temperature controlled environment. My battery experiences temperatures ranging from 10-100°F out of necessity. Not ideal. Being in a controlled environment means they sustain less deterioration during the storage period.
