Found this the other day:

http://www.powerstream.com/BatteryFAQ.html

More info than most of us need on batteries. Did you know that "the density 
of hydrogen stored in a metal hydride is higher than that of pure liquid 
hydrogen"? Cool.

There aren't too many discharge curves, but they 1) aren't linear, and 2) 
depend on the current draw. Learned a thing or two about super-capacitors 
too. Worth a read for the technically inclined.
