Battery Specifications:

Fenix ARB-L21 Series 21700 3.6 V Recommended √
Rechargeable Battery (Li-ion) 21700 3.6 V Caution* !

Warning: Do not mix batteries of different brands, sizes, capacities, or types.
*18650 and 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 tail and insert the battery with the anode side (+) towards the light head, then screw the light tail back on.

Charging:

1. Slide back the port cover on the light neck to reveal the charging port, then connect the USB Type-C end of the charging cable to the flashlight.
2. The battery level indicator will display red while charging and will turn green when fully charged.
3. Once charging is completed, be sure to unplug the charging cable and slide the anti-dust cover forward.
4. When charging fails or the battery is reverse connected, the battery level indicator will remain off or flash red to remind users to check the battery.

Note:

1. The charging time is approximately 1.5 hours from depleted to fully charged with a 9 V/3 A charging adapter. When using a 5 V/3 A non-fast charging adapter, the charging time is approximately 2.5 hours. The flashlight cannot be operated while charging.
2. Recharge a stored flashlight every four months to maintain the optimum performance of the battery.
3. This only relates to a Fenix ARB-L21 Series rechargeable battery.

Battery Level Indication:

Each time the flashlight is turned on, the battery level indicator will indicate the battery level and will last for 3 seconds. If the flashlight is turned off within 3 seconds, the battery level indicator will go out accordingly.

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 a Fenix ARB-L21 Series rechargeable 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 Low output is reached. When this happens in Low output, the battery level indicator blinks red to remind users to recharge or replace the battery in a timely manner.

*Note: This only works with a Fenix ARB-L21 Series rechargeable 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.
◎Unscrew the tail cap a few turns or take out 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 flashlight to flicker, shine intermittently or even fail to illuminate:

Problems:

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.
