probably not, 3.3V, 2.3 AH. Well, with multi-cell light they could be. That's probably what's inside the $100 sears c3 battery/charger I just ordered for pickup today
I have chargers all over the place and I like that I can charge the batteries I use (primarily 14500s and 18650s, with some 16340s and 18350s thrown in for good measure) whenever I need to or feel like it. I really don't want to buy a dozen new chargers when the 18650s and 14500s I have work just fine for what I'm using them for.
I don't rebuy the DVDs I own on Blu-Ray either.
If there was a really awesome 26650-only light, I might reconsider and get a couple of 26650s though.
You got it correct, cehoward. But that just adds to the versatility of the 26650 format. I carry a spare 18650 and reducer with me on bike rides so I can put it in any light if needed.
Between, I am a good grasshopper!! I am on my Centurion Ironman, with both the M10s up front with the Keygos cells. However, in my bag, I got spare Hi Max 18650s, and two adapters..Plus a charger too.
I have some 4sevens and Elektro Lumens lights that take 26650's...X10, S12 and Big Brute.
The power/run time advantages in the X10/S12 lights is great. I can't imagine a BB with less reserve capacity, so an 18650 in there would drain too quickly to be practical, even the 26650's are drained low enough to swap out in ~ 20-25 minutes.
I have 3 26650 flash lights and i have king kongs and have been testing a trustfire 26650 that tested well 4500 mAh.
I have ordered 3 more and sold 3 brand new king kongs i had sitting there doing nothing and i use battery spacers from IO in some of my 26650 lights to use my 18650 batteries.
Thats why i use a hobby charger, one size fits all kind of thing, plus i use 18650 to 26650 battery spacers they cost under $2.
Right now I got FIVE 26650 flashlights. Up until yesterday, I only had TWO Keygos 26650 batteries. Two Trustfire 26650 batteries arrived yesterday, with 2 more on the way. That will make SIX 26650 batteries and five 26650 lights. I ain't buying no more dam lights, no more!!
I picked up some IMR 26650's and a 4 Seven's charger a few months ago with intentions of building an SST-90 2D Mag, but that project has sort of stalled out.
