*18650 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 are considered user induced damage and are not covered by any Fenix warranty or liability.
Battery Replacement
Unscrew the light body and insert the battery with the anode side(+) towards the light head, then screw the light head back on.
Charging
- Turn off the light, open the anti-dust cover to reveal the USB Type-C charging port, and connect the USB Type-C socket 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 close the anti-dust cover to maintain the dustproof and waterproof ability.
Note:
- The normal charging time of the light is approximately 3 hours from depleted to fully charged.
- Recharge a stored light every four months to maintain optimum performance of the battery.
- The Low output or Med output can be operated while charging but the charging time will be prolonged.
* These features only works with a Fenix ARB-L18 series battery.
**The light cannot be operated without battery inserted with charging.
Battery Level Indication
With the light switched off, single click the switch to check the battery status, the indicator 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 features only works with a Fenix ARB-L18 series battery.
Intelligent Overheat Protection
The light will accumulate a lot of heat when used at high output levels 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 until Low output is reached. When this happens in Low output, the battery level indicator blinks red to remind you to replace or recharge the battery.
Usage and Maintenance
- Disassembling the sealed head can cause damage to the light and will void the warranty.
- Recharge the battery in time to ensure normal use for next time.
- Recharge a stored light every four months to maintain optimum performance of the battery.
- Fenix recommends using an excellent quality battery.
- If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage.
- Loosen the light body or take out the battery to prevent accidental activation during storage or transportation.
- Periodic cleaning of the battery contacts improves the lamp's performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons:
A: Poor battery level.
Solution: Replace or recharge the battery (Ensure the battery is inserted according to the manufacturer’s specifications).
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.
