Unleash the full potential of your Fenix flashlight with the ARB-L16-700UP—a high-performance 16340 rechargeable battery engineered for peak power, enduring runtime and absolute peace of mind. Whether you’re navigating a dark trail, working on a critical repair or simply need a reliable EDC light, this rugged cell keeps your device shining at maximum brightness longer than standard batteries.

You get the confidence to explore, work and adventure without worry.
