FENIX 18650 3400mAh (Li-Ion) - rechargeable batteries

The Fenix 18650 3400mAh (ARB-L2S) rechargeable batteries with electronics protection (protected) are based on Panasonic's top-of-the-line NCR18650B cells with improved LiNiCoO2 technology, which brings greater safety and longer life.

Li-ion rechargeable batteries are characterized by very high capacity, do not suffer from memory effect or self-discharge. Li-ion in the 18650 size are the best choice in terms of stored energy due to the size and weight of the battery.

Fenix battery protection consists of internal safety mechanisms and protective electronics. Added electronic circuits prevent the cell from overcharging, over-discharging and against short circuit or over-current draw. If the battery electronics assess that the limit values have been reached, they safely disconnect the cell.

Internal protection consists of a separator, state-of-the-art Heat Resistance Layer (HRL) protection and a special anti-blast valve. In the event that the gas pressure in the cell exceeds a certain limit, the internal separator separates the electrodes inside the battery and thus de-facto interrupts the exothermic reaction and the explosion-proof valve releases the excess gas pressure outside the battery. The combination of electronic and mechanical (temperature and pressure) protection makes the Fenix battery one of the safest li-ion batteries available.

The 18650 battery is roughly the size of two CR123A lithium batteries, which is why it is often used in flashlights as a rechargeable alternative to these primary cells. Check first whether your appliance supports this cell. This battery is designed for use in LED flashlights, LED headlamps and bike lights, for example:

Attention
If you are using an older charger purchased approx. before 2014, please check first that it will fit 69-70mm batteries. If possible, do not discharge the battery below 2.5V. Do not short-circuit the battery (do not connect the cell poles with a wire). Do not throw the battery into fire or water. Do not insert the battery into the charger in reverse (opposite polarities). When using the battery, observe the safety principles. Use only an adequate charger that supports li-ion batteries.
