Owner’s Manual
There are 3 lights on the top of the battery next to the red button. The first is
red and the other 2 lights are green. When all 3 lights are on, they indicate a
51-100% charge. When 2 lights (one red and one green) are on, they indicate
a charge of 1 to 50%. When only the red light is on, the battery is dead. For
optimal use of the battery, it would be best to recharge it when the last green
light is on.
The battery’s charge level is also visible on the LCD Control Panel.
