Fenix Flashlight ARB-L18 Overview

Power various electronics, including flashlights, camping lanterns, and much more, with this 18650 Lithium-Ion Battery with Micro-USB Charging Port from Fenix Flashlight. In addition to the conventional method of insertion into a charger, you can replenish the energy level in this cell by connecting a power cable with a Micro-USB plug. The battery features 3.6V of output power, a 3500mAh capacity, and a 12.6Wh rating.

A circuit with a durable steel shell is built into the anode to protect against overcharging, over-discharging, short-circuiting, and overheating. The last of these is prevented by a three-layer design consisting of a pressure relief valve, a microporous membrane separator, and a PTC cathode block. Additionally, the durable battery is designed to last for up to 500 charge/discharge cycles, and its low self-discharge rate allows it to maintain up to 75% of its capacity after the final cycle. As an added bonus, an LED status indicator light glows in red during charging and turns green when the process is complete.

Really good option between disposables and something that takes a dedicated charger. Always have a charger for it. So far it holds a good charge.

Fit and function are great. I bought a supposed direct replacement from a chain retailer but unfortunately it wasn't. I'd turn my light on and it'd flash maybe two seconds then go out. I'd remove/replace the end cap and get another two second flash. I returned it, got a refund then bought this battery and the light works great like it was new.

Charge on!
