The PriorityStart! battery protection system has been protecting batteries since 1997. Thousands of companies and emergency services use the PriorityStart! car battery saver each year, including Verizon Wireless, Comcast, police departments, and many more. It has been featured in Popular Mechanics, LA Times, and Motor Trend, where it was voted one of the "Top Ten Products of the Year."

The PriorityStart! car battery protector is popular with our customers because it is completely automatic and is easy to use. You can be up and running in three simple steps:

  1. Connect your existing vehicle positive cable to PriorityStart!
  2. Attach the PriorityStart! cable to your battery's positive post.
  3. Attach the ground wire to the battery's negative post.

Now, the automatic "switching" system will protect your battery if it ever drops below 11.7 volts when the engine is off, allowing the battery voltage to recover. By stepping on the brake pedal, starting power is automatically reconnected.
