Battery Voltage Tester Voltmeter / Low Voltage Buzzer Alarm Checker

It can clearly show the voltage and the state of the battery used, just plug your batteries into connectors with a black wire going first (all the way to the left) while looking at the screen.

The colours supplied will be in black as photo shows (on rare occasions white).

How to use it?

• Simply insert your battery plug into the voltage battery tester pins, and make sure that the first wire from your battery that goes onto the first pin in the battery voltage tester is black (or the colour representing black wire, maybe dark brown, etc.). After that, it will automatically show you the voltage of each battery cell and also the voltage of ALL battery cells combined. If it does not show anything, please try rotating your wire from the battery and plug it from a different side into the voltmeter to check your battery voltage.
