Extreme Max High-Efficiency Wall Mount Battery Maintainer

The High-Efficiency Wall Mount Battery Maintainer from Extreme Max is the perfect way to keep your batteries fully charged and maintained while featuring three modes of operation. Bulk Mode offers full charge strength for low charged batteries, Absorption Mode provides a high constant voltage for mostly charged batteries and Storage Mode maintains a low constant voltage for fully charged batteries. Charge time depends on both battery size and condition of the battery. Normal 15 Amp-hour batteries take approximately nine hours to get to 80 percent, while a large vehicle battery may take multiple days to reach a high charge.
