I found out from another camper we had when the convertor went bad while plugged into 110v ... the fridge would drain the battery because it still uses 12v to run the circuit board even while plugged into 110v, making the fridge inoperative.

So I think it still needs the 12V even while plugged in. I could be wrong.

I just want to make sure I don't come back to spoils in the fridge because the battery died from being dried out from charging. I'm not a expert on electrical stuff, just wondered if I disconnected the battery if the convertor would power the 12v system by itself, or if the battery was connected if the convertor knows when to not charge the battery like the trickle chargers do.
