|See The Catastrophe Fuse? Get One!|
converter/charger with one of the new modern ones that have at least 3-stage charging. It's MUCH more gentle on the batteries and shouldn't boil them to death unless it fails. Another good reason to check them even if you have one! Some of the better ones now include temperature compensation. This adjusts the charging to take the temperature of the batteries into consideration. Gentler still!
So when you check the RV periodically, make sure you check each battery and each cell to make sure you have enough liquid inside. Yes, I know it's cold or a pain in the.... you know what. But do it. You could save yourself lots of aggravation and $$$$. Take care of your batteries!!
