Fenix RCR123A 800 mAh USB-C Rechargeable Battery

Fenix lithium-ion rechargeable battery in 16340 (RCR123A) format, with a capacity of 800 mAh and a nominal voltage of 3.6 V, designed to power compact torches that accept this cell format. It charges directly via USB-C, with no external charger required, making it a practical choice for airsoft use where the torch is part of the loadout and needs to stay ready between sessions.

The 16340 format measures 16.5x34.5 mm and is physically interchangeable with a disposable CR123A cell, but delivers 3.6 V rather than 3 V: before fitting it, confirm that the host device supports this voltage, as not all torches with a CR123A compartment are compatible with lithium-ion rechargeables.

Key points

• 16340 / RCR123A format with 800 mAh capacity: replaces disposable CR123A cells in torches that accept 3.6 V cells.
• Integrated USB-C charging: no separate charger to carry in the field.
• Protection circuit against overcharge, over-discharge and short circuit.
• Compact dimensions compatible with standard CR123A compartments, but with a higher nominal voltage: always verify compatibility before use.
