17500 Battery Anyone used it?

[WmWilder]

In my planning stage on making some flashlight mods out of 3AAA LED flashlights I was researching which battery I wanted to use and found this...

This seems to be just the right size (according to the websites measurements) to replace the 3AAA pack exactly. It has more mAh than the 14500 batteries I was thinking about using and if the size is correct I would not have to make an adaptor to keep the battery from flopping around.

Has anyone tried these? Do they work or should I just try to find an 1AA flashlight instead?

I think you should be ok with an 18500 or even an 18650 if its long enough.
I have made a few 3 x aaa torch mods and they easily take the 18xxx diameter and actually need some added "packing" to take up the slack

What Vendo said. If they made a 21500 or 22500, I'd order a dozen without blinking.
