Top-quality Fenix 18650 2600 mAh rechargeable battery (ARB-L2) with protection (protected) is based on lithium-ion technology. Li-ion rechargeable batteries are characterised by very high capacity, do not suffer from memory effect and have no self-discharge. Li-ion in 18650 size are the best choice in terms of stored energy relative to the dimensions and weight of the battery.

Protection of Fenix batteries consists of internal safety mechanisms and protective electronics. Added electronic circuits prevent overcharging of the cell, excessive discharge and protect against short circuit or excessively high current draw. If the battery electronics detect that limit values have been reached, they safely disconnect the cell.

Internal protection consists of a separator, protection against overheating (PTC thermal protection) and a special anti-explosion vent. In the event that gas pressure in the cell exceeds a certain threshold, the internal separator isolates the electrodes inside the battery and thereby effectively interrupts the exothermic reaction, and the anti-explosion vent releases excess gas pressure from the battery. Thanks to the combination of electronic and mechanical (thermal and pressure) protection, the Fenix battery is among the safest available li-ion batteries.

In size, the 18650 battery corresponds to approximately two CR123A lithium batteries, which is why it is often used in torches as a rechargeable alternative to these primary cells. Check first whether your device supports this cell. This battery is designed for example for operation in Fenix LED torches LD50, Fenix LD60, Fenix SD10, Fenix E35, Fenix PD32, Fenix PD35, Fenix TK09, Fenix TK15, Fenix TK22, Fenix TK32, Fenix TK35, Fenix TK51, Fenix TK61, Fenix TK75, Fenix TK76. Fenix LED head torches HL55, Fenix HP12, Fenix HP30, Fenix HP40F and bicycle lights Fenix BT20 and Fenix BC30.

Warning

If you are using an older charger purchased around 2014 or earlier, first check whether batteries with a length of 69-70 mm will fit into it.
If possible, do not discharge the battery below 3V
Do not short-circuit the battery (do not connect the cell terminals with a conductor)
Do not throw the battery into fire or water
Never insert the battery into the charger in reverse (with opposite polarity)
When using the battery, observe safety guidelines
Use only an adequate charger that supports li-ion batteries
