Thread: Constant battery monitor

look for a battery voltage gauge--- most mid grade radar detectors have one on the display, but are availible separatly if you feel you need one.

your car should have a battery gauge on it, otherwise, as long as the car is running, you should not have any problems-- the cars electrical system should see the load as a very small audio amplifier, and should not have any problems with your electrical system unless you have made some very poor connections, or will run the computer with the engine off for very extended times (typically, more than 2 hours of runtime would be needed to run the batery down)
