Battery Specifications

**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 head, insert the batteries with the cathode side(-) towards the inner side, then screw the light head back on.

*Only half of the LEDs can be powered with a single battery inserted. In Floodlight mode, only the Med output can be operated. The brightness levels of Laser mode remain unaffected.

Charging 

1. Turn off the light and open the anti-dust cover to reveal the USB Type-C charging port. 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. When charging, the OLED display will automatically light up to show the battery percentage and a charging icon to indicate the charging status. The normal charging time is about 3.5 to 4 hours from depleted to fully charged. 
3. Charging the flashlight without any battery inserted is strictly prohibited.

*Only the Low output of Floodlight mode can be operated while charging. 

Intelligent Brightness Downshift Function

On/off 

On: with the light locked, press and hold the electronic switch for 6 seconds. The OLED display will show "ON", the light will blink twice in the Low output of Floodlight mode and then go out, indicating that this function is enabled. 

Off: with the light locked, press and hold the electronic switch for 6 seconds. The OLED display will show "OFF", the light will blink eight times in the Low output of Floodlight mode, indicating that this function is disabled.

Intelligent downshift

When the light head is close to an illuminated object (about 2.36''/60 mm) for more than 1 second, the flashlight will automatically downshift to the lowest brightness level of the current mode to avoid potential danger/burns caused by high temperatures. When the light head is away from the illuminated object for more than 1.2 seconds, the flashlight automatically recalls the previously used brightness level.

*This function operates only when the brightness level in Floodlight mode exceeds 540 lumens, or 270 lumens with one battery inserted.

OLED Smart Display

Each time the light is turned on, the OLED display will light up and show the Fenix icon for 1 second. Subsequently, it will constantly display the current brightness level, remaining runtime, and remaining battery level.

With the light turned off, single click the electronic switch to check the battery status. Single click once again and the OLED display will go out, or without any operation the OLED display will last for 3 seconds. 

Note:

1. It will take approximately one second for the flashlight to recalculate the remaining runtime after the current output/mode is changed. "CHECK" will appear on the OLED display during this time instead of the remaining runtime.
2. Only an empty battery icon will appear on the OLED display if the battery level is 5% or lower. In this state, only the Low output of Floodlight mode can be operated.
3. The remaining runtime will be reloaded if the batteries are reinserted or if their status is changed. The loading time is 5 to 8 seconds, with "LOADING" appearing on the OLED display. The light cannot be operated during loading.

Intelligent Overheat Protection

The light will accumulate a lot of heat when used for extended periods. When the light reaches a temperature of 55°C/131°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 55°C/131°F, the light will gradually recall the preset output level.

Low Voltage Warning

When the voltage level drops below the preset level, the light is programmed to downshift to a lower brightness level until the Low output of Floodlight mode is reached. When this happens in the Low output of Floodlight mode, the empty battery icon will appear on the OLED display to remind you to recharge and will continue to do so until the battery runs out.

Usage and Maintenance

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Fenix recommends using excellent quality batteries. 
• If the light will not be used for an extended period, remove the batteries, or the light could be damaged by electrolyte leakage or battery explosion.
• Lock the light or remove the batteries to prevent accidental activation during storage or transportation.
• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
• Periodic cleaning of the battery contacts improves the light's performance as dirty contacts may cause the light to flicker, shine intermittently or even fail to illuminate for the following reasons:
  A: The light is locked.
  Solution: Rotate the toggle switch clockwise to unlock and turn on the light.
  B: Poor battery level.
  Solution: Replace or recharge the batteries.
  C: The threads, PCB board contact or other contacts are dirty. 
  Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact your authorized distributor.
