Battery Monitor
Never be stranded by a dead battery again.
Don’t be stranded by a dead battery--let the Battery Monitor keep tabs on the performance of your battery every time you start your car. If cranking performance falls below 10 percent, a 30-second audio/visual alarm lets you know that it’s time to install a new battery. The easy-to-install Battery Monitor comes with flexible leads that fit all 12V battery sizes, and it connects to any style battery terminal. Patented technology monitors cranking performance and voltage, so you’ll always know your battery’s state of charge and alternator function. Rugged design features durable waterproof case. |
