All flooded lead acid batteries heat up when being charged. Charging these batteries with more than 10 amps per 100 amp hours battery capacity causes some of the charging current to dissociate the water in the batteries into hydrogen and oxygen. Of course, the dissociation is gets worse at the batteries internal temperature rises. Hit two 12 volt - 75 amp hour batteries with 50 amps for a couple hours and you are going to loose water. Those guys that equalize their batters regularly loose much more water during the process, because it is the hydrogen and oxygen bubbles that do the equalization.
