The battery watch is a smart piece of equipment which automatically detects battery voltages between 7V and 32V. It can be used to monitor approximate battery state-of-charge on 12- and 24-volt battery systems.

Three LEDs – green, red and yellow – light in various combinations to indicate battery voltage. An audio alarm can be set to sound at high or low voltage levels and all settings are programmable by the user with a push button on the front panel.
