PriorityStart! is a patented computerized device that monitors battery power when the ignition switch is off. If it detects excess voltage drain - due to lights left on, door ajar, radio on, even short circuits - it automatically disconnects the load. When the headlights are turned on, it automatically reconnects the battery and your car starts. There are no buttons, switches or hood to raise to reconnect. PriorityStart! is backed by a 12-month warranty. PriorityStart! fits both side post and top post batteries - all mounting hardware included.
