**16340/18650 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.
Battery Level Indication
Each time the flashlight is turned on, the indicator will show the current 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%
*This only works with a Fenix ARB-L18 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 preset output level.
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, the battery level indicator blinks red to remind users to replace or recharge the battery in a timely manner.
*This only works with a Fenix ARB-L18 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 flashlight could be damaged by electrolyte leakage.
Turn off and lock the flashlight 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, replace the ring with an approved spare.
Periodic cleaning of the flashlight and battery contacts improves the flashlight'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: Recharge or replace the battery.
B: The contact or contact point of the battery or flashlight is dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
If the above methods don't work, please contact the distributor.
