FENIX 18650 2600 mAh (Li-ion) USB - USB rechargeable battery

Fenix 18650 2600 mAh rechargeable battery (L18-2600U) with its own mico-USB charging connector. It can be charged by connecting the cable to the micro-USB connector (e.g. from a computer or mobile phone charger) or in a conventional charger. 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.

Fenix battery protection consists of internal safety mechanisms and protective electronics. Added electronic circuits prevent the cell from overcharging, over-discharging and against short circuit or over-current draw. If the battery electronics assess that the limits have been reached, they safely disconnect the cell.

Internal protection consists of a separator, over-temperature protection (PTC thermal protection) and a special anti-blast valve. In the event that 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-blast valve releases the excess gas pressure outside the battery. The combination of electronic and mechanical (temperature and pressure) protection makes Fenix batteries among the safest Li-ion batteries available.

The 18650 battery is roughly equivalent in size to two CR123A lithium batteries, which is why it is often used in flashlights as a rechargeable alternative to these primary cells. Please check first whether your appliance supports this cell. This battery is designed for use in LED flashlights, headlamps and bike lights, for example:

Warning! Due to the 70 mm length, it may not fit older flashlight models!

Warranty: 2 years

Caution
If you are using an older charger purchased approximately before 2014, please check first that it will fit batteries with a length of 69-70 mm. 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 that supports Li-ion batteries
