* 16340 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use quality batteries with circuit protection will reduce the potential for combustion or explosion; but cell damage or short circuiting are potential risks the user assumes.
Battery Replacement
Unscrew the light tail and insert the battery with the anode side (+) towards the light head, then screw the light tail back on.
Charging
- 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.
- The indicator will blink 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 included Fenix ARB-L16-700P rechargeable Li-ion battery is approximately 1 hour and 20 minutes from depletion to full charging.
- Recharge a stored light every four months to maintain 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: 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-L16-700P 16340 rechargeable Li-ion battery.
Intelligent Overheat Protection
The light will accumulate a lot of heat when used on relatively high 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 for the reselection of high 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 Moonlight mode is reached. When this happens in Moonlight mode, the light constantly blinks red to remind you to timely recharge or replace the battery.
Note: This only works with Fenix ARB-L16-700P 16340 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 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.
- Lock the light 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 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: The battery needs recharging or replacing.
Solution: Replace/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.
Warning
- Do place this light out of the reach of children!
- Do NOT shine the light directly into the eyes of anyone!
- Do NOT shine flammable objects at close range, to avoid burning objects or causing danger due to high temperature!
- Do NOT use the light in inappropriate ways such as biting in the mouth, to avoid personal injury or life threats when the light or internal battery fails!
- This light will accumulate a lot of heat while working, resulting in a high temperature of the flashlight Pay attention to safe use to avoid scalding.
