Fenix ARB-L21-5000 21700 Battery

3.6V | 5000mAh Capacity

Spare batteries for the Fenix PD36R have finally arrived with the release of the Fenix ARB-L21-5000 21700 battery. This 21700 battery with its 3.6 volts of power and 5000mAh capacity make it the perfect companion for high-drain flashlights, providing sufficient power and runtimes for endless use. Fitted with multiple protection systems, the Fenix ARB-L21-5000 has 3 sets of overheat protection to ensure that the battery remains at a sustainable temperature while powering your favorite lights. There are protection circuits embedded into the anode for overcharge, over-discharge, and short circuit protection as well. The steel shell riveting encasing the battery decreases any potential risk of the cell short-circuiting due to impacts, drops, or collisions combined with the pressure relief vents which will expel generated gas from a potential short-circuit to eliminate hazardous conditions within the battery. These extra steps in protecting the cell sets the Fenix ARB-L21-5000 21700 battery apart from other 21700 batteries.

Batttery is too long!
July 31, 2021
Unfortunately, the battery is too long for any of my flashlights. It might work fine in others with a longer case and/or longer travel on the contacts. For me, it was an expensive mistake.

This is the first purchase of the 21700 series of batteries. 5000mAh's is amazing. I purchased an extra battery so that, when I need a new one for the new flashlight, it is ready to install and use. Very pleased with the purchase.
