Rechargeable Li-ion Battery RCR123A 800 mAh by Fenix

Fenix ARB-L16-800UP is a modern rechargeable Li-ion battery in RCR123A (16340) size with a capacity of 800 mAh and a built-in USB-C connector. Thanks to its universal design, you can charge the battery directly via cable or using traditional chargers and compatible flashlights. The battery supports high current draw, making it a perfect choice for powerful flashlights like the Fenix E16, E18R, LD15R, and other models.
It includes comprehensive protective electronics to guard against overcharge, deep discharge, short circuit, and overheating. It also features PTC protection and a special safety valve that releases excess gas in case of overpressure, stopping internal reactions.
The battery has no memory effect and extremely low self-discharge, so it retains energy even during long-term storage. It shares the same dimensions as disposable CR123A batteries but with higher nominal voltage – always check device compatibility before use.
