Review on ProMax HD Car Truck 12V Battery Vehicle Start Protector by PriorityStart! by Tim Larsen

I have a 1993 GMC 2500 Vandura that has a short that I can't find. At first I thought it was just a bad battery or battery contact. After replacing the battery and cable, everything was fine for 3 days. Then I found myself in the bitter cold with a dead battery in a mall parking lot. I have used this unit in the past in a 1981 BMW 733i that had a similar power consumption issue and it worked. So I bought the HD version. Installing ProMax for a van took just 15 minutes. My battery still drains when I leave it at the airport for a few days BUT never below the 11.7 volt threshold where the ProMax shuts down! I simply apply the brake to generate a current that the ProMax can detect and it reconnects the battery circuit and provides more than enough backup power to run the big 550 V8. This device saves lives! It's durable, made from the best materials, easily installs in minutes and will never let you down with a dead battery again!
