Maximum temperature raise at different discharge currents: 1A:+0,3C, 2A:+0,6C, 3A:+1,3C, 5A:+2,6C, 7A:+3,6C, 10A:+4,7C, 15A:+5,3C
This is low capacity D cells from one of the big brands and as can be seen on the photos the capacity is with a fairly discrete font.

The two cells matches fairly well and can deliver the rated capacity. At high current they are considerable better than AA cells.

Conclusion

These batteries do not have more capacity than AA batteries, but are better at high current. They feel very lightweight and my guess is that they contain a smaller cell inside.
