*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 cover to reveal the USB Type-C charging port, then connect the USB Type-C end of the charging cable to the light.
2. The 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. The normal charging time of the included Fenix ARB-L21-6000 battery is approximately 3.5 hours from depleted to fully charged with a 5 V/2.5 A charging adapter.
2. Recharge a stored flashlight every four months to maintain the optimum performance of the battery.
3. When charging, all modes can be turned on, excluding Turbo, Strobe, and Colourful breathing light. However, the brightness levels may vary based on different charging statuses and battery levels.

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

*This feature 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 Eco output is reached. When this happens in Eco output, the battery level indicator blinks red to remind users to replace or recharge the battery in a timely manner.

*This feature 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.
◎Fenix recommends using an excellent quality battery.
◎If the flashlight will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage.
◎Lock the light or remove the battery to prevent accidental activation during storage or transportation.
◎Long-term use can result in O-ring wear. To maintain a proper water seal, lightly lubricate the O-ring with a tiny amount of silicone oil or grease. Replace the ring with an approved spare if worn out.
◎Periodic cleaning of the light and battery contacts improves the light's performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate.

Problems:
