Priority Start! ProMax Heavy-Duty Battery Protector keeps 12 or 24V batteries from going dead. An automatic heavy-duty computerized on/off switching system protects battery voltage and starting power. If battery voltage drains below 11.9 volts when engine is off, it automatically disconnects the load. The battery voltage immediately recovers. Just step on the brake pedal to automatically reconnect the starting power. All accessories are usable when engine is off. Transferable from vehicle to vehicle. Imported.
