The LumForce Flashlight completely operates on a rechargeable battery that is built inside the body of the Flashlight. Therefore, changing or removing the battery is not an option. If you try to remove the battery from the Flashlight, you have a perfect chance of damaging the torch, and you will not be able to use the light again. However, the package comes with a type C charging cable, one like your smartphone's charging cable, to charge the Flashlight whenever you notice that it is running out of battery.
