WirthCo Engineering Battery Doctor Battery Life Preserver Automatic Battery Disconnect

The Battery Life Preserver™ Automatic Battery Disconnect Switch is a state-of-the-art electronic device that monitors the battery's capacity. Here's the Problem: Even with the ignition off, the battery is slowly being drained by the vehicle's electronics, computer and other accessories. If the vehicle is left for an extended amount of time, the battery can drain low enough to prevent the vehicle from starting. The Solution: When the battery reaches 12.0v, the Battery Life Preserver™ switch disconnects the main power from the battery, therefore reserving enough power to start the vehicle.
