Did you happen to remove the shrink wrapped and look at the internal cell?  I am assuming this is a KP branded Samsung 20-R.  I inquired directly with KP and never received a response.  Looking at your comparator the results seem to prove out the theory.  Since there is no protection circuit I am not sure why the KP brand is worth a premium.  Interestingly enough, the 20-R OEM is no longer listed on the KP site.

No, I did not remove the schrink wrap. One thing you pay for where these cells is the button top.

Good point, I had not consider that.
