Fenix ​​18650 2600 mAh (Li-ion) rechargeable USB battery

Rechargeable battery Fenix ​​18650 2600 mAh (L18-2600U) with its own charging mico-USB connector. It can be charged by connecting the cable to the micro-USB connector (e.g. from a computer or mobile phone charger), but also in a classic charger. Li-ion rechargeable batteries are characterized by a very high capacity, they do not suffer from memory effect or self-discharge. Li-ion in the size of 18650 are the best choice in terms of stored energy due to the size and weight of the battery.

Tip: to charge a large number of batteries at once, you may want to purchase a quadruple charging micro-USB cable.

Fenix ​​battery protection consists of internal safety mechanisms and protective electronics. The added electronic circuits prevent the cell from being overcharged, its excessive discharge, and against a short circuit or excessively 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. This battery is designed, for example, for operation in LED lamps Fenix ​​E28R, E30R, Fenix ​​E35 UE (not intended for E35 V3.0), PD32 V2.0, PD35, TK11 TAC, TK15, TK16 (only 1000 lm version), 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, TK30, Zebralight, Solarforce.

The battery is also not compatible with the Fenix ​​FD65 model.
