Fenix ARB-L18-2600U USB Rechargeable Li-ion 18650 Battery

Power that actually travels with you, not a wall outlet. The ARB-L18-2600U is a standard 18650 Li-ion battery with a built-in micro USB port for charging on the move. USB cable sold separately, because apparently we still need that ergonomic mystery in the kit.

AXG Life. Life, Adventure-Ready. This battery is built for when your gear—headlamps, torches, and other 18650-powered devices—expects you to show up energized, even after long days and longer nights.

Performance / Benefits

Power your headlamps, flashlights, and other 18650-powered gear with dependable run time. The 2600 mAh capacity keeps you charged through longer outings, while the built-in micro USB port gives you easy top-ups without hunting for a dedicated charger. It’s the kind of reliability that turns midnight trail runs and questionable decisions into stories you’ll tell at the campfire—clearly and honestly, AXG-style.
