The curves tracks perfectly. The battery is only rated for 10A, but works fine at 20A with very little capacity loss.

Due to the very short discharge time I do not really see much heating.

Conclusion
This battery can deliver very impressive currents, but compared to modern batteries the capacity is way too low.
