Battery Specifications 

Warning: *21700Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using only 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 tail cap and insert the battery following the polarity marks, then screw the cap back on. 

Charging the BC26R 

1. Switch off the light and open the USB cap to reveal the USB Type-C charging port 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.
2. The indicator will display red while charging and will turn green when fully charged.
3. Once charging is completed, be sure to tighten the light head to maintain the dustproof and waterproof ability.

Note: 

1. The normal charging time of the included Fenix ARB-L21-5000is approximately 4 hours from depletion to full charging.
2. Recharge a stored light every four months to maintain the optimum performance of the battery.
3. The Low output is available while charging, but the charging time will be prolonged.

Note: This only works with Fenix ARB-L21-5000 rechargeable Li-ion battery. 

Battery Level Indication 

Each time the light is turned on, the indicator will indicate the battery level, and will stay on continuously, letting you always know your battery level as you ride. 

• 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-L21 series 21700 rechargeable Li-ion battery. 

Intelligent Overheat Protection 

The light will accumulate a lot of heat when used at 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 to reselect the modes. 

Low-voltage Warning 

When the voltage level drops below the preset level, the bicycle 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 constantly blinks red to remind you to recharge or replace the battery. Note: This only works with Fenix ARB-L21 series 21700 rechargeable Li-ion battery. 

Usage and Maintenance for the BC26R Bike Light 

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Fenix recommends using only a high-quality protected battery.
• If the light will not be used for an extended period, remove the battery for proper storage.
• Unscrew the tail cap 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 light's performance as dirty contacts may cause the light 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 bicycle light is 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.

Q3. What is the working voltage of BC26R? 

A: Voltage: 4.2V. 

Q4. Is BC26R rechargeable? How long is the charging time?  

A: BC26R is rechargeable with a USB Type-C charging port and the included 21700 battery. The charging time is about 4 hours. (The indicator will display red while charging and will turn green when fully charged.)  

Note: Once charging is completed, be sure to tighten the light head to maintain the dustproof and waterproof ability. 

Q5. How to prevent accidental activation of the BC26R? 

A: Unscrew the tail cap or remove the battery to prevent accidental activation during storage or transportation. 

Q6. Why does the BC26R downshift to a lower mode after being used for a while and the higher mode cannot be selected? 

A: There are two reasons:  

1. Intelligent Overheat Protection  

The light will accumulate a lot of heat when used at 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 to reselect the modes. 

2. Low-voltage Warning 

When the voltage level drops below the preset level, the bicycle 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 constantly blinks red to remind you to recharge or replace the battery.  

Note: This only works with Fenix ARB-L21 series 21700 rechargeable Li-ion battery. 

Q7. Why does the BC26R happen to flicker?
