The Battery Status Indicator is a device that can be added to monitor the state of power for any battery, particularly lift gate batteries, and alerts operators during pre-trip inspections that battery power may be lower than required. The LED light flashes green if battery voltage is more than 12.4 volts, or 75 percent power, and blinks red when the voltage falls below 12.39 volts.
