Description

Fenix 18650 3400 mAh rechargeable battery (ARB-L18-3400U V2.0) with its own USB-C charging connector.

It can be charged by connecting the cable to the USB-C connector (e.g. from a computer or mobile phone charger) or in a conventional charger, which can accommodate Li-ion batteries with a length of 72 millimetres. 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.

Attention! Due to the added USB-C charging connector, this battery is approximately 72 millimetres long, making it significantly longer than a regular 18650 Li-ion battery. It will therefore only fit in some flashlights, headlamps and chargers.

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 too high current draw. If the battery electronics assess that the limits have been reached, they safely disconnect the cell.

Internal protection consists of a separator, PTC thermal protection and a special pressure relief valve. In the event that the gas pressure in the cell exceeds a certain limit, the internal electronics separates the electrodes inside the battery and thus de-facto interrupts the exothermic reaction and the pressure relief valve releases the excess gas pressure outside the battery.

The combination of electronic and mechanical (temperature and pressure) protection makes Fenix batteries one of 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 device supports this battery.

Charging via USB-C connector

Plug the USB cable into the side USB-C connector, during charging the indicator light on the top of the battery is red. When the battery is fully charged, it lights blue. When using a USB power supply with a current of 1500 mA or more, the charging time is approximately 2.5 hours.

NOTICE

  • Do not discharge the battery below 3V if possible
  • 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 safety principles
  • Use only an adequate charger that supports Li-ion batteries
