Warning: Do not mix batteries of different brands, sizes, capacities or types. Doing so may cause damage to the flashlight or to the batteries being used.


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.


Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. To ensure normal use, the flashlight will not turn off automatically and will work till the battery runs out completely.


Intelligent Protection

The light will accumulate a lot of heat when used on High output level for extended periods. When the light reaches a temperature of 58°C or above, the output will automatically step down by about 1% every 1 second until to Med to reduce temperature. When the temperature is reduced, the output will gradually increase by about 1% every 5 seconds until to High. The original output of every mode is restored each time the light is switched. Note: *The above specification is from the result produced by Fenix through its laboratory testing. Actual output may vary slightly according to the working environments.


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.
  • Unscrew the tail cap half a turn 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 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 replacing. 
    Solution: Replace battery (Ensure 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.

Great little light for work, camping or just every day carry. Small but not too small and very bright on higher settings but also very useable on the lowest. For camping I love the fact that it always turns on on low and is not flooding the campground with light. 👍👍

Douglas Giachino

Great products but had a battery issue and was not covered by warranty.
But gave me a 30 percent discount for future purchase

Hi Douglas - I checked with warranty to see why the light/battery issue was not covered by warranty. They said there was corrosion in the light. Corrosion for batteries that have leaked is not covered by warranty, so we do recommend that if you aren't using a AA light for awhile that you remove the batteries, as with other products that use alkaline batteries.

My 1st Fenix

Very nice pocket lite. Easy to toggle through to the brightness you need.
Liked the idea of it using regular batteries. Very happy with it

Excellent Pocket Light

The E20 is a bright and quality built light perfect for pocket carry or glove box. Great to have a light somewhere between full size flashlight and tiny keychain light. The E20 fits this role nicely. Also uses standard batteries so easy to get new charge.

I use this everyday

This is my most used flashlight by far. It's easier to use than a phone flashlight by my bedside, and strong enough to scan my entire yard for skunks going to-and-from my car. The 2x AA's means I don't have to worry about charging up before a storm and have more juice and longer runtimes than 1x AA or 3x AAA. The size is perfect it disappears in your pocket bit is not too small like the 1x AA's. The grip is actually comfortable. Highly recommend this!
