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.

    B: The threads, PCB board contact or other contacts are dirty.

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.

    Works really well during attic inspections. For such a small light it’s awesome how bright it can be at night. Also, love the USB rechargeable option.

    Fantastic light! My only suggestion for improvement is to add a dual switch like some of the Fenix PD series. Dual switch means the on/off is instantaneous. I don’t like the extra moment of press and hold to turn the light on. But this isn’t too big of a problem and if you release too early then the only harm is simply show the current battery level, which isn’t a big deal. Plus, the press and hold time is brief and not much of a nuisance. I don’t know how Fenix is able to get such long run-times before recharge, but I’m very impressed and they are worth spending the extra money on.
