    Test Vehicle Battery Level Feature
    Although use of your vehicle's cigarette lighter adapter/12-volt DC power outlet to provide power to handheld and/or in-vehicle devices is convenient, it is important to realize that in doing so you are potentially using power that your vehicle battery needs to operate its electrical systems properly. This includes starting your motor. For this reason DC powering/charging is best done while the engine is running, allowing your battery to recharge itself. Charging can be done while the engine is off, but you risk depleting your battery if this is not done carefully. This is where the Wagan EL2537-5's vehicle battery test level functionality comes in. Consisting of a prominent series of LED lights at the top of the unit, it is designed to keep you aware of the affect your DC power charging is having on your vehicle battery. To test the current state of your battery capacity, turn off the engine for ten minutes and check the unit's LEDs. (Socket may not be live with ignition off). The EL2537-5 also allows you to monitor the status of your battery while you are charging devices via DC power outlet. In either case LED system has a light for each of the following statuses: Low, 12V, Mid and High.

    • 4 lights = good battery
    • 3 lights = normal battery
    • 2 lights = weak battery (possible fault in charging system)
    • 1 light = battery needs charging (possible fault in charging system)
    • No lights = No capacity, replace battery (voltage < 3V) and check your charging system
