Fenix 18650 3400 mAh

High-end rechargeable Fenix 18650 3400mAh (ARB-L2S) batteries with protective electronics (protected) are based on high-end Panasonic NCR18650B cells with improved LiNiCoO2 technology, which brings higher 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.

Battery protection Fenix consists of internal safety mechanisms and protective electronics. The added electronic circuits prevent overcharging of the cell, over-discharging and against short circuit or too high current draw. If the battery electronics evaluate that the limit values have been reached, it will safely disconnect the cell.

The internal protection consists of a separator, overheating protection (PTC thermal protection) and a special explosion-proof valve. If the gas pressure in the cell exceeds a certain threshold, the internal electrode separator inside the battery separates the electrodes and thus de-facto interrupts the exothermic reaction and the explosion-proof valve discharges the gas overpressure outside the battery. Thanks to the combination of electronic and mechanical (temperature and pressure) protection, Fenix batteries are among 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 lights as a rechargeable alternative to these primary cells. Check first if your appliance supports this article. The 18650 3400 mAh batteries are primarily intended for the LED lamp Fenix TK35 UE V2. 0 , but also for other LED lamps Fenix E28R, E30R, PD32 V2. 0 , PD 35 , TK11 TAC, TK 16 , TK25 UV, TK25 Red, TK26R, TK75, FD41, LD 30 , SD11, SD20. LED headlamps Fenix HM60R, HM61R, HM65R, HM65R-T, HP25R (1000lm version only), HP30R (1750lm version only), CL26Rlanterns, CL30R and Fenix BC21R and BC 30 bicycle lights.

Attention, due to the length of 70 mm and the diameter, it may not fit some old models - for example Fenix PD31, TK11, TK21, TK30.

Notice

• If you are using an older charger bought around 2014, first check that it will fit 69-70 mm batteries.
• If possible, do not discharge the battery below 2.5 V
• Do not short-circuit the battery (do not connect the cell poles with a wire)
• Do not throw the battery into fire or water
• Never insert the battery into the charger in reverse (opposite polarities)
• When using the battery, observe the safety principles
• Use only an adequate charger supporting Li-ion batteries
