Fenix 21700 5000 mAh rechargeable battery (ARB-L21-5000U) with its own charging USB-C connector. It can be charged by connecting the cable to the USB-C connector (e.g. from a computer, power bank or mobile phone charger), as well as in a classic Li-ion charger. The Fenix 21700 5000 mAh rechargeable battery is based on the top LiNiCoO2 technology, which provides greater safety and longer life. The Li-ion rechargeable battery is characterized by a very high capacity.
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.
This accumulator is designed, for example, for operation in LED lights Fenix HT18, PD36R, PD36 TAC, PD40R, TK20R V2.0, TK22 UE, E35 V3.0 and C7. However, it cannot be used in lamps for 18650 batteries due to its larger dimensions!
Due to the length of the battery of 76 millimeters (including protective electronics), it can only be charged in chargers that are adapted to this length.
