I am thinking that SOME converters may cause issue with 12v items when there is no battery hooked up, but plugged into shore power. Yes, I know a residential dehumidifier is not 12v. Maybe things like the stereo/weather radio, or CO/propane alarm, that stay live?

Yeah...I found this out the hard way. Not all converters are created equal when keeping the batts charged properly all winter (6-7 months).
I pull my RV trailer/boat/zero turn batts and move them up to the garage that gets cold but never freezes and keep a 1.5v charger on each one.
