Battery Isolator Wirthco 20092

Dividing direct current (DC) into several divisions to move the current in a single direction, battery isolator kits ensure the starting battery has enough power to restart the engine while charging itself. They are designed to enable the user to charge multiple batteries from a single power source.

Our Battery Doctor® battery isolator kits feature everything you need to isolate two batteries for independent charging through the alternator while separating the starting battery from the second battery. Conveniently packaged in an easy-to-transport case for simple storage in the trunk or under the seat, battery isolator kits also offer a parallel mode for jump-starting.
