Simple Storage of marine / boat battery

Boats frequently are allowed to sit for long periods between uses or are stored several months each year. This is a killer situation for a battery because sitting allows the battery to self discharge and the resulting low charge accelerates the build-up of sulfates on the plates.

The BLS eliminates this problem especially if used with a low rate charger during storage.
