Thought there was a thread already like this from just a few weeks ago?

Maybe, i didn’t see it.

These charts are helpful in basic general terms. What we need is a brand by brand breakdown of dimensions. As most of us have found out at one time or another, “all batteries are not created equal”. How many of you have ordered a new torch only to find that the batteries you have are 2mm too long or 1mm too fat.

“Caveat emptor”

My 18650 test does include sizes of many different brand 18650 batteries.

Generally the xxyy0 (i.e. 18650) type notation breaks down into xx=diameter, yy=length. The actual diameter can be about 0.5 mm more. For protected cells it is 0.7 mm more in diameter and up to 5 mm more in length.

Thanks for posting these. I'm going to save a copy on my battery inventory spreadsheet. I do have one disagreement, however: I checked 6 different brands of protected 18650 and width dimension is always 18mm (sometimes approaching 18.5mm); PCB addition changes the length, which can vary from 66mm to 70mm.

In case you are interested, checked these brands:
