Fenix 21700 (Li-Ion) rechargeable battery

Rechargeable battery with protection electronics offers 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.



Attention, the dimensions of the accumulator are 22 millimeters x 76.6 millimeters, so it has a larger diameter than standard Li-ion type 21700. Therefore, it only fits in some flashlights and headlamps. We have verified compatibility in these Fenix flashlights: TK17, TK22R, TK30R, HT18R, HT32, LR36R, LD45R, PD40R V3.0, PD36R V2.0, Fenix PD45R ACE, Fenix WF25RM.



The protection of Fenix accumulators consists of internal safety mechanisms and protection electronics. Added electronic circuits prevent overcharging of the cell, its excessive discharge. They protect it from short circuits or excessive current draw. If the battery electronics assess that the limit values have been reached, they will safely disconnect the cell.



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



Due to the length of the accumulator of 76.6 millimeters (including protection 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.

  • Fenix ARE-A2 charger
  • Fenix ARE-D1 USB charger

  • Fenix ARE-A4 charger
