Why does my light turn on while plugged in and charging but not when unplugged?

Most Fenix flashlights and lanterns are able to turn on while they are plugged in. While they are connected to an external power source, the light will draw power directly from the wall or other type of output source, which will allow it to turn on. 

If you find that your light turns on while charging but will not work when it is not plugged in, it is an indication that the flashlight is working but that the battery is bad. Try your battery in another device or try a different battery that you know to be good in your flashlight. If you need assistance with any warranty claim at that point you can contact our customer service department for assistance.
