The PriorityStart Battery Saver - Stops Dead Batteries

Used by many dealers, upfitters, dealerships, and, of course, our customers! The PriorityStart! line of products keeps a constant eye on your battery's voltage and automatically disconnects and cuts power to stop any undesired drain on your system. Once the engine is off, the PriorityStart will kick in if it sees the voltage drop below threshold (11.7 volts, factory setting).

Easy Installation

The universal design of the PriorityStart Battery Protectors allows installation with both top and side-post terminals.
