"Bought this for a Fenix light as well, so I knew it would fit as the light was designed for this battery (or vise versa). Again I know there a bit 'wider' than most so you do have to ensure that it will fit in your light. So far it charged well, and the light works well. Only time will tell how many re-charges I get out of it, and how it last, but so far it's working well with the nightcore charger. It's a battery, it works, and it takes a charge, not sure how much other insight I can provide."
"Very, very good 18650 battery! Worth every penny and last a very long time in my 1200 lumens flashlight."
"The batteries plastic outer-shell cracked after just one charge."
