Fenix 3500 mAh Rechargeable 18650 Li-ion Battery

The Fenix ARB-L18-3500 is a rechargeable 3500 mAh 18650 Li-Ion battery which features multiple protection points in the anode and cathode, as well as pressure relief vents to protect against gas buildup in the case of short circuiting. The ARB-L18-3500 also features no memory effect (batteries need not be drained before charging), negligible self discharge, and front and back protections of the circuit board that make it more impact-resistant and reliable.

The ARB-L18-3500 also sports a button top (as opposed to Fenix's previous 18650 cells which featured flat tops), which makes for interoperability with other flashlight manufacturer's lights (check compatibility with your specific model).
