[size=+3]Energizer D 2500mAh NH50 (Silver)[/size]
Official specifications:
Maximum temperature raise at different discharge currents: 1A:+0,3°C, 2A:+0,6°C, 3A:+1,3°C, 5A:+2,6°C, 7A:+3,6°C, 10A:+4,7°C, 15A:+5,3°C
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.
[size=+3]Conclusion[/size]
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.
