The typical vehicle battery has a minimum operating time of 1 to 2 hours, depending on the current use of the load being driven. We recommend that the operator start the vehicle every hour to recharge the battery system. this will prevent unexpected shut downs of equipment and will ensure that there is always sufficient battery capacity to start the engine.
The alarm may sound momentarily when the unit is being connected to, or disconnected from the power source. This is normal and does not indicate any problems.
