Even the DC OUTPUT VOLTAGE of only 13.6VDC that most of the RV Converter/charger use will boil out the battery fluids if left on for a long period of time. By dropping this down to just 13.2VDC stops this from happening according to Progressive Dynamics... This is what the smart mode charging units do keeping your battery safe when setting for a long time.
I learned the hard way as well... Started out in 2008 with four 12VDC Batteries using a single mode 13.6VDC converter/charger 30A unit and lost one battery rather quick by having the battery fluids boiled out. Changed the converter/charger to a smart mode unit and all has been fine since then.
