14500 batteries are lithium-ion cells that maintain similar proportions to AA batteries. Not any AA device can run off of these higher voltage cells, however, so always make sure you double check to see what cells are compatible with your device.
Powerful Lithium Ion Performance
The added voltage of a 14500 battery vs. a AA battery means you can achieve even greater performance from a compatible LED device. Fenix’s incredible flashlights are built to produce huge outputs through reliable circuitry housed in rugged materials. Among their 14500 selection is the incredibly popular and compact LD11. The Fenix LD11 is a handy every-day-carry flashlight that produces 300 lumens with the Lithium ion cell (Compared to a still respectable 130 lumens with the AA).
One of the benefits of a 14500 flashlight is the versatility of its power source. Li-Ion cells are rechargeable, so you can get hundreds of charges out of a single battery. And, thanks to Fenix’s legendary design, you can pop in a AA battery if you run out of specialty 14500 cells. You performance may drop, but you’ll have a functioning flashlight in a jam.
