Battery Specifications

Type Dimensions Nominal Voltage Recommended
Rechargeable Li-ion battery 18650* 3.6V Fenix ARB-L18 Series

Warning: *18650 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use 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
Loosen the lock catch and open the tail cap to insert the battery with the anode side (+) towards the light head, then close the tail cap and fasten the lock catch.

Intelligent Overheat Protection
The light will accumulate a lot of heat when used on Turbo output level 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 for the reselection of Turbo mode.

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, one of the battery level indicators blinks to remind you to recharge or replace the battery.

Usage and Maintenance of the Fenix WT25R Adjustable Head Flashlight

  • 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.
  • Lock the light 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.

    A: The battery needs replacing.
    Solution: Replace battery pack /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.

I was skeptical at first but after putting this thing too work for a week straight , it’s made it way into my every day work carry bag , the right angles great , the tail stand is amazing, mag tail is extremely helpful, square body shape makes sure this thing doesn’t roll away 10 feet away from me! All in all , I recommend this light to the working type, not so much a edc in the front pocket of your denim going out for the night. Who’s gonna stop you though it’s pretty compact for what ya get. This ones gonna stay with me for a while.

I’m digging this flashlight I put it to work the day I got it! Clipping it on my work apron , sticking it to the door on my work truck bins , and throwing it tailstanding under a sink ! The shapes nice also no more rolling away , tail standing is nice for jotting down some quick notes also on a table or even the hood of my truck. I’m super happy with this new style ! Gonna be putting through its paces for sure.

    I bought the Flashlight because I just like them, bought this one because the other one I was gifted (PD36R) was unbelievable in performance. So I bought this and first time I used it, someone knocked it off the counter and it fell apart, after long search, I found. the parts. I started using it in my line of work, light is everything, everyplace and with the folding head, the magnetic base I use it everywhere and seldom use my other, it lets me shine a light without putting the flashlight in my mouth to hold, would never trade it, give it away. When I leave home, it comes with me.

    I’ll NEVER GO BACK to round!

    Honestly the flashlight itself was great. But the moment I used the magnetic feature it all went south… I’m an elevator mechanic and need a strong magnet while working in the elevator shaft. To make a long story short… it fell 200 + feet the second day in use… I was pretty bummed out and didn’t want to be one those guys that contacted you to ask for a refund. I think I’m going to just stick with a headlamp… That being said I Love your company and will continue to use your lights in the future. Thank you

    Great light, but wish it was made of mostly aluminum.
