I assume having the charging port/controller IN the battery itself significantly decreased the capacity
Edit: I guess since they are lithium they can pack more capacity in the decreased space as compared to alkaline or NiMh

FYI, I've been bench testing these for a bit, the phantom drain on these is like nothing I've ever seen.
Maybe I got a bad set, but I fully charged a batch, dropped them into a headlamp, and went to use it a week later and it was completely dim and then shut down. Lithium ion batteries absolutely should not do that. Coast has a fantastic warranty, and Costco purchases are of course 90% bullet-proof, but thought I should share my experience.

Did you try putting those batteries on a different device. I have the same issue with a flashlight.All the rechargeable batteries do the same thing. I think that's a device issue.
