How are you charging the battery if the inverter is out of the loop?

What is the Year, make and Model of the RV?

During normal operation the inverter charges the battery, if the inverter is bypassed it should not be charging unless it was somehow wired to the bypass, that would be a big problem. Normally what you have to do to have DC power is put a charger on the batteries to keep them up. Also the batteries could be bad and should be load tested when they cool off and are not gassing at all, I would shut everything down and let things cool off and then remove the batteries. You do not want to remove them when they are gassing as if you provide a spark accidentally you can have an explosion, so best to shut everything down for a few hours then disconnect them, have them tested and replaced if needed. I would advise a charger on the batteries if you need DC power, or just get by with the AC power if you can.

Let me know if you have more questions or concerns...... Robert

I'm charging the batteries with a small standalone charger. It's a 2002 40' Teton 5th Wheel. It has (4) 12 volt batteries and one of the batteries was completely dry and swelling the case. I refilled the battery, disconnected the charger for about 4 hours. When I returned from work the same battery was leaking acid and the caps were pushed up.
RV Mechanic: Robert, RV Mechanic replied 7 months ago

That battery sounds like it could be bad but I would have them all load tested really can not replace a new battery with weaker ones or it will bring the new battery down. Need to be careful with that battery if it is swelling. IF anything you can take it out of the loop and run with three or two and see what happens, all the positives will go to each battery and the negatives. So you could easily remove one or two from the circuit.....
