The discharge curves match very well and the capacity is just about constant at any discharge current below rating.

Conclusion
For its time an impressive tool cell, but the capacity is low by today’s standard.
Notes and links
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
How is the test done and how to read the charts
How is a protected LiIon battery constructed
More about button top and flat top batteries
Compare to 18650 and other batteries

Thanks for the test HKJ

How many of these out-of-date batteries you got from Vapcell are in the pipeline still?

I do still have a nice pile from of cells, but they are never (That means 2xxxmAh).
It was very nice of Vapcell, because I have not had much else to test on the 2800mAh and below test station.
I did also get some never cell.
