The PriorityStart! ProMax from BLI is an automatic computerized voltage disconnect/reconnect system that protects a car’s battery, alternator, and electrical system. The microprocessor and gear drive system have been redesigned for 2007. PriorityStart! now has a battery power on/off indicator as part of its circuit. A red light means high voltage has disconnected the battery. A green light means the battery power has been automatically reconnected. While the unit cannot save a bad battery, it can prevent the typical battery drain that keeps a car’s engine from starting, preventing aggravation, tow bills, and down time.
