The battery does very fine up to 3A load, that is 2C and matches the rated 2C maximum discharge. Drawing much more than 3A does not really work.

Conclusion

The performance looks average for 18500 batteries, but they are not designed for high current.
I will call the cells acceptable.

Thanks. The 1700mAH seems a better value unless you're sure you're going to confine them to a non-demanding application.
