Who should use the PriorityStart! 12-Volt ProMax H.D.?

  • Law Enforcement, Work trucks, and Heavy Duty vehicles
  • Any vehicles with increased electrical/load demands
  • PriorityStart! is the only automatic computerized on/off protection system for your battery, alternator, and electrical system in the market today. If battery voltage drains below 11.7 volts when engine is off, it automatically DISCONNECTS the load, leaving starting power.

    To RECONNECT and START: simply step on the brake pedal, activate headlights, or operate any other accessory, and starting power is RECONNECTED! No buttons to push, no switches to flip, and there is no hardwiring. It's positive to positive, with a ground wire, and you're done.

    No waiting for service or emergency trucks. No need for jump-starts (jump-starting damages the battery, alternator and potential major damage to computers and electrical system). No more down time or lost man hours. It is preventative maintenance that pays for itself 1st time it saves you.

    Using portable battery chargers/boosters, dangerous jumper cables, or calling a tow truck means you have already experienced a damaged battery (first time battery goes dead it has lost 1/2 its service life).

    Universal design fits top and side post batteries. No hardwiring or modifications required. Transferable. Manufactured to ISO, USCG, and SAE standards.
