"Love these Fenix protected batteries with built-in USB charger. Fenix 18650’s and assorted adapters run everything I will need."







The newest addition to Fenix's already high-caliber line of rechargeable batteries, the Fenix ARB-L18 2600U 18650 Battery is one of the most reliable and innovative batteries on the market today! Featuring incredibly potent Lithium Ion chemistry, this impressive cell delivers 3.7 Volts of power and can hold a sizable charge of 2600 mAh, providing your high-drain devices with the energy they need for extensive use. But with great power comes great responsibility, and this 18650 comes with plenty of protections to ensure it functions safely. From built-in pressure relief valves in case the battery gets too hot to intelligent protection circuits to ensure there are no short circuits, this battery is as safe as it is effective.
For the first time ever, Fenix is offering a battery that does not need a designated charger in order to recharge, a helpful feature that will make charging on the go quick and easy. In addition to being used in conventional Li-Ion chargers, the ARB-L18-2600U is designed with a convenient micro-USB port located on its side, allowing it to be refueled by one of the most common charging cables available! The cell even comes with a multi-colored LED power indicator that will let you monitor the charging progress of your cell and know when charging is complete.

"Love these Fenix protected batteries with built-in USB charger. Fenix 18650’s and assorted adapters run everything I will need."
"Good performance, but be sure your device can handle a cell that is actually 18. 5 x 70 mm (rather than the 18 x 65 one might otherwise expect)."
"Customer service was just great and the items arrived on time and as ordered. Put a charge on them just fine . . . now we'll see how well they hold up. Thank you."
"Excellent battery easy to charge"
