Low-voltage Warning Function

  1. When the working battery voltage is detected lower than 3.3V, the indicator light will shine automatically to remind charging needed.
  2. When the working battery voltage continues to drop lower, the flashlight will downshift to a lower brightness level. When it happens in low output mode, the flashlight will blink three times every five minutes to remind you to recharge the flashlight. To ensure normal use, the flashlight will not turn off automatically until Over-discharge Protection stops the battery from working.

Over-discharge Protection

When the battery voltage is extremely low, the flashlight will turn off automatically to protect the battery from over-discharging.

Over-heat Protection

The flashlight will accumulate a lot of heat when it is working at Turbo output. When the light is overheated up to 65 ℃ or above, the flashlight will automatically downshift the output to prevent the light from overheating. Please reset the Turbo output if needed when temperature drops.

Intelligent Memory Circuit

The flashlight memorizes the last used brightness level except strobe function. The next time you turn it on, it will recall the previously used brightness level in General Mode and Simplified Mode.


Put the flashlight head into the charger cradle and rotate it until it clicks into the position, match the polarity port of the flashlight and the cradle’s.

When power connects, the indicator light of the charging cradle will turn green without flashlight, the indicator light will turn red with flashlight plugged in, then turns green when charging completely done. The normal charging time is about 3 hours.

  1. Please charge the RC20 when the light is off to permit full and fast recharging.
  2. If emergency lighting is needed, the flashlight is available at Mid output level when it is charging.

Note: Please recharge a stored RC20 every four months to maintain optimum performance of the battery.

Battery Replacement

Unscrew the tail cap to insert Fenix ARB-L1 series rechargeable Li-ion battery, no need to identify the polarity mark, and then screw the tail cap back on.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using 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 or battery explosion.
  • Unscrew the tail cap one-half turn or take out the battery to prevent accidental activation during storage or transport.
  • Continuous working at Turbo brightness level, the light may activate over-heat protection or light beam trembling, to maintain normal status, please lower the brightness level to cool down the flashlight.
  • 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 flashlight’s performance as dirty contacts may cause the flashlight to flicker, shine intermittently or even fail to illuminate for the following reasons:
    Reason A: The batteries need replacing.
    Solution: Replace batteries (Please confirm the correct installation of anode and cathode).
    Reason 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 refer to the warranty policy before contacting your authorized distributor.

Notice: The routine cleaning video can be watched and downloaded through Fenix official website, please log onto the service channel->“maintenance for light”.


The flashlight is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the light directly into anyone’s eyes.

    Without a doubt one the most powerful flashlights I’ve ever owned. On my first use I spotted two coyotes eyes looking back at me from approximately 100 yards away in woods while walking my dog at night. Without the extreme lighting features of this light I would have proceeded deeper into the woods and possibly be attacked. The light it gave off quite literally saved me and the dog.

    All of my Fenix lights are great. It’s the wall mountable cradle charger that sets this one apart.
    Perfect for home, work, but expecially on a boat where things are in constant motion

    I bought this light hoping it would meet the demand I put on it. It does, and it does it well. I mounted the cradle in my pickup, and I drive all night on some of the roughest, rockiest, washboard caliche roads around. I wasn’t sure the light would stay in the cradle, or that it would rattle to high heaven and I would throw it out with my sanity. I was gladly mistaken with my assumptions.

    The light is bright, it’s tough, well made cradle. I couldn’t be happier and wouldn’t recommend any other light but a fenix
