Unprotected flat top 14500 is the same size as AA. A button top may add a mm and protection add a couple of mm

I do not know how to post pictures on here. But for sure it has a PCB and much longer than regular AA. The reason is one of my lights uses AA x 2. I can not fit them in at all. Both 14500 are longer.

The 14500 is 1/4” longer than AA for sure. I measured it.

The name brand is Digital Energy World. Sold a few years ago at Radioshack.

I hope you weren’t going to put 2×14500 in a 2xAA light, even if they would fit.

Just discovered this wonderful addiction.

Why not please? Then that means I might end up making spacer if only 1 is used?

If AA are in parallel and your flashligt works also with 14500 you can, but if is it in seriese not because you will have 8.4V instead or 3V.

14500 is about the same size as an AA, but its a 3.7V battery. AA batteries are 1.5V. You can find 14500 batteries that are compatible though with AA batteries.

Both batteries will be installed with + end towards head and next battery right behind it. That is the reason I can not fit both in there. Both 14500 will be 1/2” longer.

If you got the 14500s in order to have rechargeable batteries, look into getting some Eneloop AA instead. They will be the correct voltage for your light and are high quality.

And now that you have some 14500s, now you can add to your collection and buy a light that takes them. Smile Just make sure the light you get specifically says it will take protected 14500s.

“The HyperCAGE features an industrial design that is nearly unbreakable. Drop it from 100 feet and dunk it 3 meters under water, it can handle it.”

It survives a 100 foot drop. That’s impressive!

That is reason I own 2 of them. Just wanted to use 14500. But I will settle on Eneloops if not viable for 14500.

I got several 14500s now.

The Sofirn 14500 is noticeably shorter, even with its button top, it’s just as tall as the shoulder of the Fujitsu (LSD NiMh).

The Hixon is a protected 14500 and is notably much taller than a regular AA (it’s also slightly fatter in diameter).

The PKCell is a flat-top (on the second PKCell in the picture, I placed a disc magnet on top of it so it can function as a button-top temporarily on flashlights that require button tops)
