Dual battery tester

This compact and robust device displays the voltages of either the leisure battery or the starter battery. It clearly illustrates the battery voltage range from deep discharge to maximum charging voltage. The LED display provides a fairly accurate reading of the battery voltages. A button press selects the leisure or starter battery voltage, or switches the display off. Red indicators signal the need for recharging when the battery voltage is low. Connection is made via screw terminals on the back of the device. Its small front panel dimensions and exceptionally shallow mounting depth of only 15 mm allow for installation almost anywhere, leaving the storage space behind it unused.
