Why isolate your batteries?
Many vehicles have multiple batteries: one to start the engine and others to power accessories.
Without a Battery Isolator (BI), a battery with a lower charge will rob power from a battery with a
higher charge, until the batteries equalize. This problem is known as multiple battery drain and could leave you with dead batteries.
The solution
To eliminate the multi-battery drain problem, a Battery Isolator acts as a check valve between the batteries, preventing the current from flowing from one battery to another. Each battery is isolated and acts as an independent power source. So no matter how drained your accessory batteries become, they will never drain power from the battery you’re depending on to start your engine.
When the alternator is charging, current can only flow from one direction, from the alternator to the batteries. Each battery then determines the amount of current which flows into it by its own state of charge based on the voltage regulator setting. With this system, the alternator is protected, the batteries are protected. The balanced circuit electronic isolator is the absolutely the best way that proper isolation and control can be accomplished, solving every multi-battery drain problem.
