Dimensions of Nitecore IMR18350?

[fuyume]

Does anyone have the published or measured dimensions of the Nitecore IMR18350 battery? I have been running a Fenix ARB-L16-700UP (16340) battery in my Nitecore EC11 because I didn't have an external charger and I wanted a battery with a built-in USB charger. Now that Nitecore has their new NL1816R USB-C 18350 (40.8mm±0.3mm, according to their website), I'd like to know how it compares to the IMR18350, so I can tell whether or not I can use it in my EC11.

I've found conflicting figures online, at 35.5, 36.2, and 36.5 mm overall length for various versions.
