Can be fitted with two different types of batteries?18650 or 26650??

Both types will work. You need to use the included spacers with the 18650s. I haven't tried to mix and match both at the same time but I doubt that was your question. Use the tube extender to get the highest output. The extra bat makes a big difference. 26650 are optimal but are not as common and take up two charging slots so you may have to wait to charge the other battery if you don't have another charger. This thing is only ~50 bucks now. Pretty good deal.

I only have the 26650 battery. However, I seem to recall a description advising both were permitted.

Yes. As long as they are alternating between each size of battery. Won't work in series. I use my flashlight all the type and I use two different size batteries.

Yes, It comes with plastic adapters. Also the tube adapts to 2 0r 3 batteries.

It comes with a plastic spacer for the 18650 batteries to work. I have only used one type at a time but they both work. I see more light output with the 26650 batteries. I suggest buying some even if you already have some 18650s. I have the Fenix TK 75 which is comparable to this light with 26650 batteries. This one has more spread, the TK 75 has better throw. Lumen ratings are way off but this is a good light for the price.

They are both 3.7V and typically you can add a sleeve to an 18650 battery to be used in lieu of a 26650, but the 26650 is larger in diameter than a 18650 and a 26650 can NOT be used for a LED flash fitted for a 18650.

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

I have never substituted a "three AAA adapter" for an 18650 battery. I much prefer the rechargeable 18650s over the AAAs. Additionally, I have never seen a three AAA adapter the same diameter as an 18650. My suggestion would be to invest in 18650s, with a charger, and use those. I also suggest getting the 18650s with built in protection against overheat. They're easy to find on Amazon.

Matt, Buy the Trustfire 26650s if this is the 7 or 11 led torch. I own the 7 @ 8500 retina melting lumens. It will work on 2 or 3 18650s or 26650s. I use 3 26650s an they last hours on high. This beast lights up a whole acre! Don't forget to get the universal battery charger.Steve

the use of a 18650 battery requires a separate extension piece to accommodate the 18650s length, the one I acquired and works with this flashlight to be able to use the 18650 battery; http://www.amazon.com/dp/B00DAXPGNK

No, but you can use the CR123A, just don't use more than 3, and of course the 18650, and 3 of them as well.

18650 type. Get some quality batteries like Sony VTC5's, avoid any of these you can see on amazon called Ultrafire or anything like that.

i just looked that flashlight up on amazon and it said it takes 2-cr123a or 1-... 18650 and that is the battery you are asking about ...so yes you can use that battery

Electrically yes, physically NO. Both are 3.7V li-ion, both are 65mm long. The 18650 has a diameter of 18mm, the 26650 has a diameter of 26mm.

Can't be. An 18650 is WAY bigger than a CR123A and has 2-3,000 mAh. In a word...unpossible.

It won't ,I order the same flashlight from a different company with a 26650 battery & charger. The new light is about 15% larger and battery works great. Good luck

No. The 26650 is the same length, but it's too wide to fit in the battery tube. The first 4 numbers are the size. 26mm x 65mm. Most li-ion batteries are similar.16340 = 16mm x 34mm etc.

The 18650 battery is larger than a AA battery in diamter and length. It is about equal to two CR123A batteries stacked together and in some cases interchangeable. The 18650 puts out a little more power than two CR123A. The Obtronics batteries I purchased have worked perfectly for over a year now.

no, you can do the opposite with an adapter 18650 with adapter will replace a 26650

Ive used it with one single 18650 and with 3ea AAA NiMH batteries in the holder. But what I'm curious about is will it work using 2ea 18350 batteries loaded?
