Battery Specifications

• Fenix ARB-L21 series (21700, 3.6V): Recommended.
• Rechargeable Battery, Li-ion (21700, 3.6V): Caution — do not use a 16340 or 18650 battery.
• Rechargeable Battery, Li-ion (18650, 3.6V): Banned.

Do not mix batteries of different brands, sizes, capacities, or types. 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 could lead to combustion; using quality batteries with circuit protection reduces this risk.

Battery Replacement

Unscrew the light body and insert the batteries with the anode side (+) towards the light head, then screw the light body back on. The flashlight can be used with only one battery inserted, but brightness will be affected.

Charging

Turn off the flashlight and open the anti-dust cover, then connect the USB Type-C end of the charging cable to the light and the other end to a charging adapter. When charging, the five indicators flash green left to right; normal charging time is about 4 hours from depleted to full. The LR35R Pro recognizes PD3.0, PD2.0, other fast-charging protocols, and standard 5V adapters (max charging current 3A, 2.5A on 5V input). Do not charge the flashlight if there is no battery inserted.

Battery Level Indication

With the light off (locked or unlocked), single click the electronic switch to check the battery status; the indicator(s) also show on power-on and last 3 seconds.

• Five lights on: 100% - 80%.
• Four lights on: 80% - 60%.
• Three lights on: 60% - 40%.
• Two lights on: 40% - 20%.
• One light on: 20% - 1%.

Low-Voltage Warning

When the voltage level drops below the preset level, the flashlight downshifts to a lower brightness level until the lowest output is reached. When this happens, one battery level indicator blinks to remind users to recharge or replace the batteries.

Intelligent Brightness Downshift Function

When the light head is close to an illuminated object (about 60 mm) for more than 1.5 seconds, the flashlight automatically downshifts to 50 lumens to avoid danger caused by high temperatures. When the light head is away from the object for more than 0.8 seconds, the flashlight recalls the previously used brightness level. To turn this function on or off, lock the light and press and hold the electronic switch for 6 seconds — two blinks on Floodlight Low means enabled, six blinks means disabled.

Intelligent Overheat Protection

The flashlight will accumulate heat at high output levels for extended periods. When it reaches 55°C/131°F or above, it automatically steps down a few lumens to reduce temperature, and gradually recalls the preset output level once the temperature drops below 55°C/131°F.

Usage and Maintenance

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Fenix recommends using excellent quality batteries.
• If the light will not be used for an extended period, remove the batteries, or the light could be damaged by electrolyte leakage.
• Lock the light, unscrew the light body half a turn, or take out the batteries 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 light and battery contacts improves performance as dirty contacts may cause flickering or failure to illuminate: the flashlight may be locked (unlock by rotating the toggle switch clockwise); the battery level may be poor (recharge or replace); or the contacts may be dirty (clean with a cotton swab soaked in rubbing alcohol).
• If the above methods don't work, please contact the distributor.
