18650 in AA box

[degnr8]

Looking at doing a couple new box mods and wanted to move up to the 18650s. What I don't know though, is will they fit in a AA box?

 

[Vapant]

AA batteries are 14mm diameter and 50mm long so no, 18650s won't fit but 14500s would.

What vapant said
Plus this bit of info for future reference:

When reading the numbers of a cell, here's the breakdown of what they mean:
(always measured in millimeters)

First two numbers are the cell's diameter.
The third and fourth numbers are the cell's length.

The last number depicts the shape of the cell. (0 stands for cylindrical).

Example: 14500(aka AA sized lithium cell)
14 = 14mm diameter
50 = 50mm length
0 = cylinder shape

So for the 18650
18mm diameter
65mm length

Keeping in mind that protected cells will have a few millimeters added in length. The protection usually does not affect the diameter significantly.

Yeah, I've used 14500s on most of my earlier mods, but wanted the higher mah I can get out of the 18650s. Since the 15mm difference worked out to just over 1/2" I wasn't sure if I could cram 'em in or not. Guess I'll have to look for bigger boxes or make my own.

18650 boxes are fairly readily available

Would something like this work for you?

Thanks for the link,wonder if an Okr-t chip would fit in there.

Yup, have to get one or two of those and probably some 3 and 4 batt versions. (I'm going to see if I can build an all week vape )
