This is a older high capacity cell (Datasheet from 2012), it is not designed to deliver high current.

The discharge curves matches very nicely, datasheet only shows discharge curves up to 2C, i.e. around 4A, but it can handle more.

Conclusion
This was a very good cell some years ago, today both the capacity and the current ability is rather low.
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

Hello HKJ, thanks for another of your reviews!

The link for this cell below the “latest additions” on your website doesn’t show this review. Instead the 18650 comparator appears.
