The Tail Lift Battery Guard has been developed specifically to protect the engine
starting batteries from being excessively drained by the tail lift to a point where
there is insufficient voltage to start the vehicle.
Using the technology from our other Battery Guard products, the Tail Lift Battery
Guard monitors the available battery power when the tail lift is in use, if the
battery voltage drops below 24.1v (12.1v) a 4 minute voltage sensitive timer is
triggered on the ECU.
If the voltage remains below 24.1 volts uniformly for 2 minutes, the sounder on the
ECU will begin to bleep.
