Product description
Fenix battery protection consists of internal safety mechanisms and protective electronics. The added electronic circuits prevent the cell from being overcharged, its excessive discharge, against a short circuit or too high current consumption. If the battery electronics evaluates reaching the limit values, it safely disconnects the cell.
Internal protection consists of a separator, protection against overheating (PTC thermal protection) and a special anti-explosion valve. If 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 anti-explosion valve releases the excess gas pressure 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 size of the 18650 accumulator corresponds to roughly 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.
Compatibility: lamps Fenix E28R, E30R, Fenix E35 UE (not intended for E35 V3.0), PD32 V2.0, PD35, TK11 TAC, TK15, TK16 (1000 lm version only), TK25 UV, TK25 IR, TK25 Red , TK25 R&B, TK26R, TK75, FD41, LD30, SD11, SD20. Fenix HL55, HL60R, HP25R, HP30R, HM61R, HM65R, HM65R-T LED headlamps, CL26R, CL30R lanterns and Fenix BC21R and BC30 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.
