The perfect alternative to standard AA alkaline batteries, the Fenix ARB-L14-2200U is a rechargeable battery that works in many devices that require this type of power. It is the same size and voltage as a standard AA, but has a built in USB Type-C port which allows you to recharge the battery for up to 300 cycles. Better performance with multiple circuit design protections, makes this a much better choice—and is better for the environment.

I’ve got one in my headlamp and one in my wireless mouse, and it’s nice not swapping out alkalines every couple weeks. The 2200mAh capacity holds up through a full evening of camping without sagging. Same size as a standard AA, so it drops right into everything I own.

Stella Q. ★★★★★ Aug 13, 2026

The voltage stays rock-solid in my flashlight even as the charge dips, which my old rechargeables definitely didn't do. It's been through dozens of cycles already and still holds a full charge like it's brand new.

Took these camping for a weekend and my little lantern ran the whole time on one charge. The fact that they're the same size as regular AA batteries meant I could pop them straight into my headlamp with no adapters. Drain is pretty even across both cells too, which I didn't expect.
