How to use:

Check the battery level.Simply connect the positive/negative electrode of the battery to the positive/negative electrode of the charge indicator plate.The current battery level is measured by pressing the trigger switch.Four leds divide the total battery capacity into four segments.At the flick of a switch, you know how much power the battery has

Package includes:

1 x Battery Indicator
