Battery Guard 2000 - 200 Amps

Product Code: BAT-116-01

£369.00

The Battery Guard constantly monitors available battery power when the engine is not running, if the battery voltage falls below 12.1v or 24.1v a voltage sensitive timer in the ECU is triggered.

If the available battery voltage remains below 12.1v or 24.1v uniformly for 2 minutes, the Battery Guard ECU provides an output that can drive a buzzer and activate a dash mounted reset switch which will be flashing.

If the voltage remains below 12.1v or 24.1v uniformly for a full four minutes, the batteries will be automatically isolated, to guarantee starting power. At this stage there will be no power at the ignition switch, the vehicle operator must press the flashing reset switch and then start the engine within the four minute timer period.

Battery Guard also offers the vehicle operator the ability to manually isolate the batteries via the Battery Guard reset switch.
