The battery monitor is a handy aid, for example in car use. It ensures that you don’t encounter a situation where an appliance such as a cooler drains the car or boat battery to the extent that the vehicle cannot be started. The battery monitor measures voltage. When it falls below 11.2 V, the device switches off the electricity from the appliance, be it a television, a cooler or a light fitting. Model EC-991.
