Product information

Description

Fenix ARB-L18-2600U is a rechargeable Li‑Ion battery designed for devices that accept 18650 cells and for applications where CR123A‑type form factor replacements are used. The cell measures 18.6 × 70 mm and provides a nominal voltage of 3.6 V with a rated capacity of 2600 mAh. This USB‑chargeable 18650 offers integrated protection circuitry, pressure relief vents and a button‑top design to ensure safe installation and operation in compatible torches and portable electronics.

Advantages

The ARB-L18-2600U combines the higher energy density of lithium‑ion chemistry with built‑in safety features: protection circuits to reduce risks from short circuits, over‑charge and over‑discharge, and pressure relief vents to release gas in the unlikely event of an internal failure. Being rechargeable reduces long‑term operating costs and waste compared with disposable CR123A cells, while the USB charging option enables convenient recharging without a separate external charger. The cell is compatible with devices that accept 18650 batteries and can be used as a replacement where two CR123A cells are specified.

Suitable for

  • High‑output flashlights and torches designed for 18650 cells or replacement of 2×CR123A
  • Portable lighting for outdoor activities, work sites and emergency kits
  • Handheld electronics and equipment requiring a 3.6 V rechargeable power source

Key specifications

  • Battery chemistry: Lithium‑Ion (Li‑Ion)
  • Nominal voltage: 3.6 V
  • Rated capacity: 2600 mAh
  • Cell size (diameter × length): 18.6 mm × 70 mm (18650 format)
  • Form factor compatibility: 18650 and as a replacement for devices using 2×CR123A
  • Built‑in protection circuitry: short‑circuit, over‑charge and over‑discharge protection
  • Pressure relief vents for safety under internal fault conditions
  • Button‑top design for compatibility with a wide range of devices
  • USB charging: integrated Micro‑USB charging port; recommended charging current 1 A, maximum 2 A; USB port charging 1 A
  • Guaranteed cycle life: designed to retain at least ~75% capacity for up to 500 charge cycles

How to use

Insert the battery into the device following the polarity markings on the battery and the device. For USB charging, connect a suitable Micro‑USB cable (not included) to the battery’s charging port and to a compatible USB power source. Use the recommended charging current (around 1 A) and avoid exceeding the maximum recommended current. Do not attempt to charge the cell in a charger not intended for protected Li‑Ion cells. Use the button‑top orientation as required by your flashlight or device to ensure reliable contact.

Usage recommendations

Store and charge the battery in a dry, cool place away from direct heat. Only use trustworthy USB power supplies and cables. Do not expose the battery to water or prolonged high temperatures, do not puncture or disassemble the cell, and replace the battery if it shows signs of damage, swelling or unusual heat during use or charging.
