If your Fenix flashlight or headlamp uses an 18350 cell, it pays to have a reliable replacement or spare battery at hand. The Fenix ARB-L18-1600 is a rechargeable Li-ion battery with a capacity of 1600 mAh, suitable for example for the Fenix PD26R ACE, TK05R, GL23R and GL19R V2.0 flashlights and the Fenix HM53R Garnet and HM55R headlamps.

Multiple cell protection

The protection circuit prevents overcharging, over-discharging, short circuits and excessive current draw, and safely disconnects the cell when limit values are reached. Inside, the battery is protected by a separator, an HRL (Heat Resistance Layer) against overheating and an anti-explosion valve that vents excess gas pressure outside the battery.

Li-ion with no memory effect

Li-ion technology offers a high ratio of stored energy to cell weight and has no memory effect, so you can top up the battery at any time. It lasts 500 charge cycles and can be charged in standard Li-ion battery chargers.
