My Damon Challengers battery is boiling when its plugged into shore power for an hour or so, it reads 13.5 volts going into it, and 13.2 after I hit the disconnect. Is my invertor supposed to shut off the charge when its full or is my battery just shot? Thanks for any help!
The converter should shut down once the battery is fully charged. Could be a converter not shutting down. If you can disconnect from the charger for a couple of days and see if the batteries hold their charge than you might know if you have bad batteries, otherwise if you have a way to check them it should answer your question.
Update, I installed two new deep cycle marine batteries and the charge went to 14.5 volts then dropped to 14.1 and held steady, they are not hot at all, so I'll monitor them for the next few trips and see what happens.
