RetroSound Exile

If your garage is full of vintage cars, lawnmowers, ATVs, and other motorized vehicles, it can be challenging to keep track of which vehicle is charged up — especially those that have to sit through seasonal storage. The Exile EM-1 LED battery monitor from RetroSound makes it easy to check your battery's status with just a glance. The red, yellow, and green lights will let you know what's ready to go and what needs a charge. Warranty: 1 year
