The two cell match nicely and can easily deliver the rated 4A.

Conclusion
This looks like a good 18500 cell. Capacity is high for the size, but it is not a high current cell in any way.

Thanks HKJ! Much appreciated! I could not find the cell in the comparator though. Was I just missing it?

I do not know why it is missing, I have started a new build of the comparator and will upload it when it is finished. Then it may take some time before it is pushed to the website or maybe it is a cache that has to timeout.
Check in an hour or two if it is included.
