I have a 1995 H-29.5 with what appears to be the standard battery charger system. The charger is a Dytek brand charger, white in color but no helpful informtion on the exterior. I assume it's installed either at the Hunter factory or by the dealer. My question: is this a "smart" multi-stage charger or is it simply an oudated one that throws a constant charge into the battery system and eventually, if left running long term, would fry or shorten the life of my bank of batteries?
