How about the 18650 battery? Does it worked on this light?

No in the PC20 You really can really only use CR123 or RCR123 batteries. The diameter of the 18650 is too big.

The 18650 battery fits perfect in my PC20, not sure why Harris Outdoors claims it won't fit.

Any 18650 battery will do. The higher the mAh you buy the in these the longer the light will run between charges. I'd stick with name brand 18650's BTW - Panasonic, Samsung, etc. The low cost/low quality 18650 are certainly cheap but they can be dangerous.

I have no idea what a 18650 battery is, but from the other responses, it looks like the answer is , NO.

Hey, it uses cr123's (2) . 18650s are just slightly too big to fit in the tube. It's a pretty good flashlight ; however, I gave mine to my brother. For pretty much the same price the Fenix PD32 UE or PD35 are vastly superior lights in lumen capacity, function and user interface, as well as build quality.

Yes. It's still an 18650 which is the main part you should be looking for, this battery just has more mAh than the one you're taking about.

Ben, it is probably the type of battery. I had the same problem with a flashlight,and had to get batteries from Hong Kong to get the light to work.

It fits fine . Use any color nail polish on the screws to help them stay in from vibration I it's on an AR15. Def get the 18650 Battery it throws more light the battery is better than using 123 batteries but it's nice to use either . I use te light all the time and it is holding up so far

I purchased 3.7V 18650 3000mah Rechargeable Batterys. They seem to work well. I've used them for about a year so far.

You should have no problems with that battery. I hooked up the light to a 12V supply I have. The light uses 0.8A.

Yes I use a Nuon 18650 2600 mAh and 3.6V it works great. Two of the cr123 work great also just make sure to use the included plastic sleeve to keep them from rattling. The light itself works great I've used some surefires and 5.11's and I prefer the O-light

I have the same light and the three (3) 26650 batteries and they fit fine. The 18650 batteries are the same length as the 26650, the only differences are the mAH rating and the 26650 are twice the size in diameter. Your flashlight should consist of four (4) body pieces which are the switch cap, two (2) body pieces, and the light assembly. If the light won't screw all the together I would check the switch cap and the for something that may have gotten stuck inside.

Sorry. I have the 44901 lithium not the 44900 std battery. FWIW. Amp draw has to be marginal Best flashlight I've ever owned BTW.

The 18650s that came with it have a button top. The battery contacts in the headlamp do have a small protrusion that might make contact even with the flat top battery and there is a pretty decent spring to provide pressure, but all of my 18650s have the button top so I can't test it.

No, The ones with the XML-T6 LED's only work with the 18650 battery. The ones you mention that work with AA look similar to this one but are small and use the Q5 LED just look for what type of LED it used as there are multiple brands of each. The AA version's are cheaper and great to stock up on. Good luck

An 18650 rechargeable. Do not put 2 18350's in there. They will fit but it will destroy the light.

No the 18650 is too large the 14500 will work as well as 1 AA battery. I have several of these flash lights, buy it you'll love it.

I use the 18650 batteries , And yes I do believe there is a difference between the two batteries I think its brighter with the 18650
