What types of batteries can be charged by ProMariner and On Board Solutions chargers?
A. AGM, Lead acid, and G.E.L. batteries can be charged. The chargers are factory set for lead-acid batteries. The settings depend on the type of charger, different models may have different settings, but most of our chargers have a lead-acid and a gel-cell setting. AGM batteries will charge at the lead-acid setting (NOT the gel setting). Some chargers carry 3 types of battery type profiles.
