Last night around 9 PM, we heard what sounded like a gunshot. Went out and looked around. No clues. This morning I see that one of the two 12V batteries on the tongue of my 20 ft trailer had exploded!...
Same for your car battery. Keep the water topped of and use distilled water only.
Agree on two 6 volt batts if you have room. Marine 12v batts are not the right choice for an RV, they are an ideal compromise for a boat to start the gas motor, and be able to run the electric trolling motor a little, then start the gas motor again. Otherwise they are not great. I dont know why the RV industry uses them, or how that got started...
