What batteries should I use for the Fenix TK16 (V1) tactical flashlight?Updated 2 years ago
Any Fenix 18650 battery will work well in the Fenix TK16 (V1) tactical flashlight. The higher mAh the battery has, the longer runtimes you'll see with the LED flashlight. Please be aware that whatever 18650 battery you choose needs to be a button top battery to work in the flashlight.
