*Do not mix batteries of different brands, sizes, capacities, or types.
*Do not use 18650, CR123A, or 16340 batteries.
*21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using low-quality batteries or mishandling batteries (such as short-circuiting or overheating) could lead to combustion and jeopardize the safety of users and property. Any adverse effects resulting from the use of low-quality batteries are not covered by any Fenix warranty or liability. Using quality batteries with circuit protection will reduce the potential for combustion or explosion.

Battery Replacement:

Unscrew the light body and insert the battery with the anode side (+) towards the light head, then screw the light body back on.

Charging:

1. Turn off the flashlight and open the anti-dust cap to reveal the charging port, then connect the USB Type-C end of the charging cable to the light.
2. The battery level indicator will display red while charging and will turn green when fully charged.
3. Once charging is completed, be sure to unplug the charging cable and close the anti-dust cover.

Note:

1. When charging fails or the battery is reverse connected, the battery level indicator will flash red to remind users to check the battery.
2. The charging time of the included Fenix ARB-L21-5000 V2.0 battery is about 1.5 hours from depleted to fully charged with a 5 V/2 A charging adapter.
3. The flashlight cannot be operated while charging.

*Note: This only works with a Fenix ARB-L21 Series battery.

Battery Level Indication:

Each time the flashlight is turned on, the indicator will indicate the battery level and will last for 3 seconds.

Green light on: saturated 100% - 85%
Green light flashes: sufficient 85% - 50%
Red light on: poor 50% - 25%
Red light flashes: critical 25% - 1%

*Note: This only works with a Fenix ARB-L21 Series battery.

Intelligent Overheat Protection:

The flashlight will accumulate a lot of heat when used at high output levels for extended periods. When the flashlight reaches a temperature of 60°C/140°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C/140°F, the flashlight will gradually recall the pre-set output level.

Low-voltage Warning:

When the voltage level drops below the pre-set level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output, the battery level indicator blinks red to remind users to recharge or replace the battery in a timely manner.

*Note: This only works with a Fenix ARB-L21 Series battery.

Usage and Maintenance:

◎Disassembling the sealed head can cause damage to the flashlight and will void the warranty.
◎Recharge the battery in time to ensure normal use for next time.
◎Fenix recommends using an excellent quality battery.
◎If the flashlight will not be used for an extended period, remove the battery, or the flashlight could be damaged by electrolyte leakage or explosion.
