Rechargeable battery Fenix ARB-L16-700UP (RCR123A, 16340) with its own micro-USB charging port. It can be charged by plugging a cable into the micro-USB port (e.g., from a computer or a mobile phone charger), in a classic charger, and in rechargeable flashlights and headlamps. Compared to the ARB-L16-700U battery, it is adapted for a higher discharge current (up to 2.5 A). It is an ideal solution especially for models that do not have their own charging port, such as Fenix GL06, Fenix GL07, or Fenix GL22. It also serves well as a spare battery for flashlights like Fenix E18R V2.0, Fenix HM50R V2.0, Fenix HM51R V3.0, Fenix PD25R, and others.

Battery protection can be divided into two areas. The first includes added electronic circuits that prevent overcharging of the cell (a situation where classic li-ion batteries risk explosion) or, conversely, its over-discharging (the battery could not be recharged). Additionally, these circuits protect the battery against short circuits or high current draw, which could damage the battery. If the battery electronics detect that limit values have been reached, they disconnect the cell. The second area is protection against overheating (PTC thermal protection) and a special anti-explosive valve. Unlike other valves used in li-ion batteries, when the gas pressure in the cell exceeds a certain limit, this valve separates the electrodes inside the battery, de facto stopping the exothermic reaction and releasing the excess gas pressure outside the battery. Thanks to the combination of electronic and mechanical (temperature and pressure) protection, Fenix batteries are among the safest li-ion batteries available.

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

It is also suitable for older models: Fenix HM51R (incl. V2.0), Fenix E15 XP-G2, Fenix E16, Fenix RC09, CL09, Fenix PD22 Ultimate Edition, Fenix PD25, Fenix E18, and LD15R.

WARNING - do not use in Fenix E15 (does not apply to E15 XP-G2), PD10, PD12, PD20, PD22 (does not apply to Ultimate Edition), and HL50, as there is a risk of damaging the electronics!

Due to its length of 35.5 mm, it may not fit into older flashlight models!

Charging

The battery can be charged:

• Via the micro-USB port: Plug the USB cable into the side micro-USB port; the indicator on top of the battery glows red during charging. It turns blue when fully charged.
• In a flashlight or a headlamp: The battery can also be charged in rechargeable flashlights and headlamps. It can be used as a spare battery for headlamps like the HM50R V2.0, HM51R V2.0, and flashlights like the E18R and LD15R.
• In a standard charger for Li-ion batteries
