This battery can
Me in a Thrunite flashlight I bought awhile back and since then I have bought several more flashlights. Tried using the battery in another brand light and it will not fit! This particular battery was designed for Thrunite flashlights and no other. It will fit some different brand lights but most it won't. So hopefully you read the instructions before you buy this cell for something other than Thrunite product because chances are it won't fit in the battery tube! It's larger than most other 21700 batteries made.
