My flashlight has a rechargeable battery but you have to use a charging station. The Klarus 14GT-92UR 14500 battery has a charging port on the battery. All I need is a charging cable I can just plug in to charge. No charging station needed. I love it! Thank you Klarus. Tom

it performs well in extreme conditions

I was skeptical about 800mAh in this size, but these batteries proved me wrong,. I've already bought backups

Huge upgrade. My flashlight runs noticeably brighter with this battery.

The battery itself is excellent—no complaints!
