OB1, brand name generally doesn't tell you nearly as much about how well a battery works as researching the technology behind it does. Of course, there is the matter of the manufacturing standards of the company to keep in mind and all...
What does the NiMH designation stand for? Nickel Cadmium rechargebles (I forget that one's designation), for those who haven't used them, just plain suck. They tend to lose their charge rather quickly, both in terms of overall life and the fact that the power dropoff is pretty instant so most devices with a warning light of some kind saying when the power is getting low tend not to give you enough warning. Li-Ion would be great put into the standard sizes, but that's a tough thing to do simply due to the way it works. They could take the flat ionized sheets and wrap it all up like a rug I suppose (haven't thought it out myself), but the question is if they could get all that to fit in the space needed and still provide the power needed for that battery type. Oh yes, Nickel Cadmium also has a "battery memory" issue I believe, namely that over time parts of the overall circuit set up in the battery can break down if the battery is repeatedly only half charged which means that the battery basically has it's capacity reduced. It is frickin' tough to get the battery back to normal. Anyway, due to that, even though rechargebles had been around even in my childhood, I never used them. They just sucked was all...
But yeah, back to the question, what is NiMH?
Edit: Oh that's what they are.

And also.. it stands for Nickel-Metal Hydride. Apparently they store 150% of the energy of the old NiCA batteries as well as having no "memory effect".

"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." ~ Charles Babbage (1791-1871)
