This battery is rated as a super high draing battery (This is some years ago).
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.
This battery can deliver very impressive currents, but compared to modern batteries the capacity is way too low.
