Fenix ​​21700 (Li-Ion) rechargeable battery

The rechargeable battery with electronic protection delivers the highest real capacity on the market. Li-ion rechargeable batteries are characterized by very high capacity, do not suffer from memory effect or self-discharge.

Please note that the dimensions of the battery are 22 millimeters x 76.6 millimeters, so it has a larger diameter than regular Li-ion type 21700. It will therefore only fit into some lamps and headlamps. We have verified compatibility in these Fenix ​​lights: TK17, TK22R, TK30R, HT18R, HT32, LR36R, LD45R, PD40R V3.0, PD36R V2.0, Fenix ​​PD45R ACE, Fenix ​​WF25RM.

Fenix ​​battery protection consists of internal safety mechanisms and protective electronics. Added electronic circuits prevent the cell from being overcharged or over-discharged. They protect it from short circuit or excessive current consumption. If the battery electronics evaluates reaching the limit values, it safely disconnects the cell.

Internal protection consists of a separator, state-of-the-art overheating protection (HRL - Heat Resistance Layer) and a special explosion-proof valve. If the gas pressure in the cell exceeds a certain limit, the internal separator separates the electrodes inside the battery, de facto interrupting the exothermic reaction, and the anti-explosion valve releases the excess gas pressure outside the battery.

Due to the battery's length of 76.6 millimeters (including protective electronics), it can only be charged in chargers that are adapted to this length and are listed below. It will not fit in other models.
