This PriorityStart! battery protector is specially designed for Law Enforcement, Fleets, Utility, Emergency, and Security vehicles with multiple accessories. PriorityStart! 12v battery protector is an automatic computerized on/off “switching” system protecting battery voltage and starting power. If battery voltage drains below 11.7 volts when engine is off, it automatically disconnects the load. The battery voltage immediately recovers. TO START: just step on brake pedal, starting power is automatically reconnected. Designed to handle 1000 “starting amps”.
Often multiple accessories mimic “engine run”. The Pro-Series is specially designed to handle multiple accessory loads, utilizing higher value electrical components to monitor “engine run” when the engine is off.
Pro-Series is successfully being used in vehicles with:
- 2 way/CB radios
- Radar Systems
- Cell phones
- Flashlight Chargers
- Mobile Equipment
- Dual batteries
- Hi-Amp Stereo Systems
- Mobile T.V
PriorityStart! battery protector is an electronic cut off switch. It will not charge or maintain a battery.

installed this on a Mercedes with multiple battery draw issues, cheaper to install this than to fix all the customers issues
only problem was the way Mercedes wires everything, if it disconnects it needs to see a load on the negative side of the battery, I had to wire in a push button switch to be able to do a reconnect after the battery voltage dropped.
The PriorityStart was a godsend for the huge oversight in the engineering of the 2008 Toyota Highlander Hybrid I bought a year ago. The Hybrid has a tiny 12V battery (like a garden tractor battery) which runs the computer, which allows the actual humungous hybrid battery to start the car. Well, this little baby battery would go dead all the time, sometimes for reasons unknown. And there I'd be stuck. After getting stuck three hours away from home on a Sunday night, I finally bit the bullet and sprung for the PriorityStart. Now when someone leaves a door ajar, or a dome light on, or someone forgot to push the button to turn off the smart key function, the battery only drops to 11.7 volts and then saves itself by cutting the power to everything. Yes, it is annoying when I lose my pre-sets for the radio and the clock, but it is no longer a life changing event. I push the brake pedal and the system re-sets and away I go. I have never been left stuck since. And this little baby battery has gone dead many times. Two things about the install: The rubber band they supply with this is a joke. Such a good product should be ashamed to even send something like this. After a somewhat tricky (but not crazy) install due to space limitations, about a week later the whole unit slid up on the battery, the positive cover slid off, and it was arching against the hood, causing the ABS system to judder and showing all kinds of warnings on the dash lights when hitting the brakes, especially going downhill. It was like it was shorting out the whole car! Very scary. My advice is to immediately throw away that rubber band (mine snapped) and find a more secure way to strap unit to battery (I used an industrial sized tie wrap). Then secure the positive post cover with another tie wrap, disallowing it from ever contacting metal. After draining the battery to zero multiple times before installing the PriorityStart, I probably should have replaced the battery AFTER installing this device. It's been about 8 months now, and this unit has kept peace between me and this otherwise decent vehicle. I would have sold it otherwise.
Installed on a 2014 Kia Sorrento that was frequently not starting due to dead battery. Kia says that's life, get used to it, so many computers.
The Pro Start was a bear to install in this car because of the very short + battery cable.
Works though, no more dead battery!
My Navigator would drain the battery after a few days of sitting in the yard. I could not find out why so I constantly had to jump start it. Now with the "Priority Start" installed, Problem Solved!!!
My mother's car had a battery drain that everyone has looked for.. Battery would run down unless the car was driven every day. This was the quick and easy solution.
it works right.leaves plenty of power to start.easly resets by pushing brake.awesome I was so tired of jumpn off every 3 days. allready replaced battery this saved me time and hassel before runied another. I wish it came with mount thats sold seperatly but its so solid its not going anywhere just would of looked better. will do again!!!
This worked good when I first installed it but
now it may work or it may not work. The cable that
comes with it is way to short it should come with
a lot longer cable. The ground wire is also not
