Fenix ARB-L16-700UP rechargeable battery (RCR123A, 16340) with built-in micro-USB charging connector. You can charge it by connecting a cable to the micro-USB connector (for example from a computer or mobile phone charger), as well as in a conventional charger. Compared to the ARB-L16-700U and ARB-L16-700 batteries, it is designed for higher discharge current (up to 2.5 A). It is therefore particularly suitable for devices with higher current consumption, for example Fenix E16 and Fenix E18R torches. Li-ion technology provides one of the best ratios of stored energy to cell weight. Batteries have no memory effect and self-discharge is minimal.

Battery protection can be divided into two areas. In the first, electronic circuits are added that prevent overcharging of the cell (a situation where conventional li-ion batteries risk explosion) or conversely excessive discharge (the battery would then not recharge). Additionally, these circuits protect the battery against short circuit or high current draw that could damage the battery. If the battery electronics detect that limit values have been reached, they disconnect the cell. The second area is then protection against overheating (PTC thermal protection) and a special anti-explosion valve. Unlike other valves used in li-ion batteries, this one, when the gas pressure in the cell exceeds a certain threshold, separates the electrodes inside the battery and thereby effectively interrupts the exothermic reaction and releases excess gas pressure outside the battery. Thanks to the combination of electronic and mechanical (thermal and pressure) protection, Fenix batteries are among the safest available li-ion batteries.

In size, the battery corresponds to the RCR123 disposable lithium CR123A battery, which is why it is often used in torches as a rechargeable alternative to these disposable cells. Check the first time whether your device supports this cell, as it has higher nominal voltage compared to the disposable battery. These batteries can also be used in torches such as Fenix E15 XP-G2, Fenix PD25, Fenix RC09, Fenix HM50R, Fenix HM51R, Fenix PD22 Ultimate Edition.
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, risk of electronics damage! Due to the length of 35.5 mm, it may not fit in older torch models!
