Charging

1, First switch off the light and plug the USB A socket of the charging cable into an electrical outlet, then connect the USB Type-C socket 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 close the anti-dust cover to maintain the dustproof and waterproof ability.

Note:

1, The normal charging time of the included Fenix ARB-L21-5000 V2.0 rechargeable Li-ion battery is approximately 3 hours from depletion to full charging.
2, Recharge a stored light every four months to maintain optimum performance of the battery.
3, The light is unavailable while charging and do not remove the battery during charging.

Battery Level Indication

Each time the light 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 Fenix ARB-L21 series 21700 rechargeable Li-ion battery.

Intelligent Overheat Protection

The light will accumulate a lot of heat when used on High or Turbo modes for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user the reselection of High or Turbo modes.

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the battery level indicator constantly blinks red to remind you to timely recharge or replace the battery.

Note: This only works with Fenix ARB-L21 series 21700 rechargeable Li-ion battery.

Usage and Maintenance

 - Disassembling the sealed head can cause damage to the light and will void the warranty.
 - Fenix recommends using only a high-quality protected battery.
