Why drive without a battery indicator, when we never drive without a fuel indicator? After all, vehicles cannot even start if a flat battery is under the hood.

The Battery Monitoring System is designed for in-car use. Its simple, easy to read display lets users determine the status of the battery and the alternator at a glance! If the battery needs to be replaced, or if the alternator is overcharging your battery, a buzzer sounds, warning you of an impending battery failure.

Installation is easy and no drilling is needed. With the Battery Monitoring System, you'll NEVER get caught with a dead battery at the most inappropriate of times!
