Well, standard LSD type batteries, such as Eneloops, Fujitsu, Amazon, and older Duraloops are in the 1900mAh (min.) to 2000mAh.
Higher capacity NiMH batteries can be lumped into two camps: low self discharge and high self discharge.
LSD high caps are in that 2400mAh-2500mAh range and these would be Eneloop Pros, Fujitsu 2450mAh, Duracell Ion Core 2450 and some Amazons.
We don't get nearly the cycle life out of them, that we see with standard LSD types. Figure on 200-300 cycles, but IME, about 2-3 years, whichever comes first. They also don't hold a charge as long as the standards, over time, but they can offer about 25% more juice, so they have their place.
Finally, we have the high discharge type NiMH that stay charge for a month and start to sail south on us. These can be my long defunct Sanyo 2700s and my AccuPower 2900s. PowerEx/Maha had their 2700s as well. There are others and they're usually sourced from China, although my Sanyos were made in Japan.
Probably slightly higher in capacity than the LSD high caps, but with similar (shorter) longevity before internal resistances start spiking and they need recycling.
If you use batteries quickly, say in a camera flash, baby chair, or game controller, the high caps should be your choice, but you're replace them sooner, regardless of cycles.
