Very interesting. When someone gets a few, can they post OD measurements if possible? I am assuming the OD will be exactly the same as the 2200 18650's, but you never know...
OK, just got mine........no measurements, just practical observations.......I have a Ultrafire C1 which is my tightest body light, the button top AW 18650's just fit snugly, some of them I have to shake out, these still have the sticker on them............now, the new 2600mAh cells are slightly tighter to push in, I took the sticker of the fattest cell I bought and now it fits the same as the older one with the sticker on....so no problem with the width.....The length is noticed only when three are in line, so over the length of three cells the difference between these and the older ones is 2.0 mm longer.....I now have mine in a 3x 18650 Solarforce and my 3x 18650 WE Rattlesnake (with the stickers on)
Unless you have a very tight body that just fits the older cell without a sticker, or you have a very short head and/or tail spring in your 3x 18650 light.........then you should have no problem at all with these new AW 2600 mAh cells.
