The Battery Status Indicator from Phillips Industries is designed to let technicians know whether a vehicle's battery has all the power it needs. The Phillips Battery Status Indicator is a simple device which can be added to monitor the state of power for any battery, particularly lift gate batteries. It alerts operators during pre-trip inspections that battery power may be lower than required. If battery voltage is greater than 12.4 volts or 75 percent power, the LED light flashes green. If the voltage falls below 12.39 volts, the light will blink red indicating that batteries should be charged before the trailer leaves on the next trip. Phillips new Battery Status Indicator, part number 60-9000, is available through Phillips authorized distributors.
