*18350 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only using quality batteries with circuit protection will reduce the potential for combustion or explosion. Cell damage or short circuiting caused by using this type of battery is considered user induced damage and is not covered by any Fenix warranty or liability.
Battery Replacement
Unscrew the light head and insert the battery with the anode side (+) towards the light head, then screw the light head back on.
Charging
- Turn off the light and open the anti-dust cover to reveal the charging port, then connect the USB Type-C end of the charging cable to the light.
- The indicator will display red while charging and will turn green when fully charged.
- Once charging is completed, be sure to unplug the charging cable and close the anti-dust cover.
Note:
- The light cannot be operated while charging.
- Recharge the battery promptly to ensure its normal life expectancy.
- The normal charging time of the light is approximately 2 hours from depleted to fully charged.
- Recharge a stored light every four months to maintain the optimum performance of the battery.
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: 100% - 85%
Green light flashes: 85% - 50%
Red light on: 50% - 25%
Red light flashes: 25% - 1%
*This feature only works with a Fenix ARB-L18-1100 18350 rechargeable battery.
Intelligent Overheat Protection
The light will accumulate a lot of heat when used for extended periods. When the light reaches a temperature of 60°C/140°F or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C/140°F, the light automatically recalls the previously used 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. When the voltage level is still too low, the battery level indicator will blink red rapidly to remind you to recharge or replace the battery.
*This feature only works with a Fenix ARB-L18-1100 18350 rechargeable battery.
Usage and Maintenance
- Disassembling the sealed head can cause damage to the light and will void the warranty.
- Fenix recommends using an excellent quality battery.
- If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
- If burnt powder residue coats the lens, try cleaning it with a glass cleaner or mild solvent.
- Remove the battery to prevent accidental activation.
- Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
- Since gun maintenance requires the use of organic solvents, organic solvents contaminating key internal components of the light may cause malfunctions, and the light will not receive normal warranty service.
- 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: Poor battery level.
Solution: Replace or recharge the battery.
B: 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.
