Rechargeable Li-ion battery Fenix ARB-L14-1050 (14500) with protection (protected) is based on lithium-ion technology. 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 have been added that prevent overcharging of the cell (a situation where classic li-ion batteries carry a risk of explosion) or conversely excessive discharge (the accumulator would then not be able to recharge). Additionally, these circuits protect the battery against short circuit or high current draw, which could damage the accumulator. If the battery electronics determine that limit values have been reached, they disconnect the cell. In the second area is 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 accumulator. Thanks to the combination of electronic and mechanical (thermal and pressure) protection, Fenix batteries are among the safest available li-ion accumulators.

In size, the 14500 accumulator roughly corresponds to a classic AA battery, but has approximately 3 times higher voltage. Therefore it can only be used to power torches and head torches that support this higher voltage. It can be used for example in Fenix RC05, Fenix LD09 (220 lumens version only), Fenix LD11, Fenix LD12 (320 lumens version only), Fenix LD12R, Fenix LD22 V2.0, Fenix E25 Ultimate Edition, Fenix HL35 head torch. Please check first whether your device supports this cell.

Warning

• If possible, do not discharge the accumulator below 2.5 V
• Do not short-circuit the accumulator (do not connect the cell poles with a conductor)
• Do not throw the accumulator into fire
• Never insert the accumulator into the charger in reverse (with opposite polarity)
• When using the accumulator, observe safety principles
• Use only an adequate charger that supports li-ion accumulators
