List of Li Ion Battery Sizes

[Ez Duzit]

Found this today. Seems to cover most of them.

10180 battery - 10mm x 18mm (1/3 AAA size)
10280 battery - 10mm x 28mm (1/2 AAA size)
10440 battery - 10mm x 44mm (AAA size)
14250 battery - 14mm x 25mm (1/2 AA size)
14500 battery - 14mm x 50mm (AA size)
16340 battery - 16mm x 34mm (nominal CR123a size)
17335 battery - 17mm x 35mm (nominal CR123a size)
17500 battery - 17mm x 50mm - slightly wider than CR-123, but 1.5 times the height of the typical CR-123a battery - two of these will generally replace three of the CR-123a batteries

17670 battery - 17mm x 67mm - about the size of two CR-123a batteries, but less overall voltage, 4.2v max vs. 6v max from two primary batteries

18500 battery - 18mm x 50mm - wider than CR-123a, about 1.5 times the height of a single CR-123a battery, these will only fit lights designed for their wider size

18650 battery - 18mm x 65mm - wider than CR-123a, about 2x the height of a single CR-123a battery, these will only fit lights designed for them

Great list Ez Duzit. This should help out the first time modders out there and perhaps some experienced modders as well.

This is one of those post you have no reason to respond to but feel it's necessary. Closed sticky?

Great list. The only thing missing that would probably help would be to list the mAh rating (or range).

It's also missing the cr2 (15270), 18350 and (less important) 18490.

I agree. A sticky for this one may be helpful.

should 17335 be 17mm *33.5mm?

 

[LinuxBozo]

Definitely agree this deserves a sticky. Sounds like the 17670 is a great alternative to the 18650 for those folks who have flashlight mods that won't quite fit the 18650.
