Reviews
Not sure if the batteries
"Not sure if the batteries don't last a long time, or it's the headlamp. But not what I expected. Good quality, just don't last a long time. I guess unless I don't want to light anything up, which defeats the purpose."
Good quality batteries that I
"Good quality batteries that I can trust. They hold the charge well and are dependable in extreme weather."
Headlamp holds charge again!
"Holds charge for several hours again with the new battery. The battery and new headband brought my old headlamp back to new."
Forever Batteries
"These last forever! And work better in my other brand lights than their brand"
Great batteries
"I needed new batteries for my Fenix bike light and these are perfect! They fit properly (no rattle, not too fat). They charge properly and last a long time."
Perfect battery for the best
"Perfect battery for the best flashlight."
Used in colder, but not
"Used in colder, but not that cold, weather (40-55 degree F) for adventure racing world championships. Raced for 8 nights, 9 days. Used on the lowest setting to preserve light. Not sure if it was the cold, but my light died after 4 hrs of riding. Super disappointing when you have 8hrs of dark left to bike!"
Not what they used to be
"I purchased a few Fenix flashlights several years ago. They have worked great. Unfortunately when I recently bought a replacement battery (18650) it was not of the same quality. It only holds a charge for a few days, and is barely useful. I don't know if I got a "dud" or if they are all like this now. Bummer."
Batteries
"Better longer lasting per charge than any other brand I’ve ever tried and I’ve used several different brands over the years and nothing comes close to these plus headlamps will last all day long 12 hours easily I recommend getting a separate charger for recharging batteries biggest game changer"
