Battery Isolators

Battery isolators are best seen as the distribution point of an automotive electrical system. Generally built with diodes, isolators ensure that charge is evenly distributed between multiple batteries and the alternator.

Battery Isolators eliminate multi-battery drain when two or more battery banks are in a charging system. These function as a check valve between the batteries and the alternator, allowing current to only flow in one direction, from the alternator to the batteries. Quality and reliability are the cornerstone of our battery isolator selection, featuring leading manufacturers such as EATON and Cole Hersee.
