I keep one of my cars in a locked garage at my work. Because I do not drive it that much the battery always seemed to drain down. Since I do not have the time to do a lot of trouble shooting with this, I bought a unit called PRIORITY START from a supporting vendor.
This unit uses some type of relay to monitor the battery voltage and will then disconnect the load to the battery, and use some type of bypass to keep the battery from discharging.
When trying to start the car, there is a 3 second delay, you can hear the module gears move, and the car starts like the battery was new.
It was easy to install. The positive cable attaches to the unit, and the unit then attaches to the positive terminal. This was the first time in almost 6 months that I was able to start the car without a jump after letting it sit for a week. Now I can move on to more urgent problems like getting my 73 running again.
Priority Start
Guarantees Battery Power For Starting
Saves Your Battery
Simple Installation - 3 Easy Connections
Offers Security, Safety & Peace of Mind
Priority Start is a patented computerized device that monitors battery power when the ignition switch is off. If it detects excess voltage drain - due to lights left on, door ajar, radio on, even short circuits - it automatically disconnects the load. When the headlights are turned on, it automatically reconnects the battery and your car starts. There are no buttons, switches or hood to raise to reconnect. Priority Start is backed by a 3-year warranty. Priority Start fits both side post and top post batteries - all mounting hardware included.
I bought a disconnect switch also. Just in case this unit did not work I was going to go with the disconnect route. But I wanted a more high tech method of keeping the battery at a level that the car would start when I wanted to go for a ride.
