There are two means of charging battery:
1) To charge the battery with the charger: Locate the DC power
source port of the tool. With dry hands, connect the tool to the
charger and plug in the charger to start charging.
2) To charge battery by USB cable: Locate the USB port of the tool.
With dry hands, connect the tool to a PC with the USB cable to
start charging.
 The battery will begin charging automatically. While the
battery is charging, the charging indicator light is red.
 When the battery is fully charged, the charging indicator light
turns green.
 Once the battery is charged, it may remain until it is ready to be
used. There is no risk of over-charging the battery. When the
battery has been fully charged, the charger automatically
switches to retention charging.
 Unplug the charger from outlet once charging completes.
