Additional Product Information
How Does It Work?

The Sure Power isolator serves as a check valve between your batteries, stopping the current from flowing from one battery to the next. Each battery is isolated and becomes an independent power source. So no matter how drained your accessory batteries become, they will never drain power from your main engine battery.

When current is drawn from battery #2, the check valve stops current coming from battery #1. When an alternator is charging, the current can only flow in one direction, from the alternator to the batteries. Each battery can then determine the amount of current that flows into it by its own state of charge based on the voltage regulator setting.

Using this system, your alternator is protected, the batteries are protected, and most importantly, you and your family or passengers are protected.
