Top rechargeable Li-ion battery Fenix ARB-L16-1150P (size RCR123A / 16340) comes with a remarkably high capacity of 1150 mAh. This ensures significantly longer runtime for your devices. It is an ideal choice for high-drain flashlights and headlamps such as Fenix E18R V2.0, Fenix HM50R V2.0, Fenix HM51R V3.0, Fenix Vitae and Fenix PD25R. This battery can be charged directly in charging flashlights or in external chargers. Thanks to modern Li-ion technology it does not suffer from memory effect and has minimal self-discharge, so it is always ready for use.

Fenix ARB-L16-1150P is among the safest Li-ion batteries on the market thanks to its two-stage protection:

1. Electronic protection: Integrated circuitry at the positive pole guards the battery against overcharging, excessive discharging, short circuit and high current draw. If limit values are reached, the electronics safely disconnect the cell.
2. Mechanical protection: Inside the battery there is a separator, overheat protection (PTC) and a special pressure-relief vent.

In size it corresponds to the RCR123A standard and serves as a rechargeable alternative to disposable CR123A batteries. However, check compatibility before purchase: this battery has a higher nominal voltage (3.6 V) compared to disposable batteries (3 V).

It is also suitable for models: Fenix HM51R (incl. V2.0), Fenix E15 XP-G2, Fenix E16, Fenix RC09, CL09, Fenix PD22 Ultimate Edition and LD15R.

WARNING – do not use in older models: Fenix E15 (does not apply to the XP-G2 version), PD10, PD12, PD20, PD22 (does not apply to the Ultimate Edition) and HL50. The higher voltage could damage their electronics!
