There are many many batteries out there that if you'd look around - you could get alot cheaper... like watch batteries.
Check out an LR6 battery some time... it's a stack of 4 1.5VDC button cell batteries in a foil wrapper, which equals 6VDC.
Just about every Ni-MH battery pack I've ever taken apart has had a series of standard-cell batteries in it. it's only a "pack" because they're wrapped up and have tab-leads soldered to them, which is quite easy to take care of.

I'd like to think that people might open their eyes at some point... instead, I find it more and more likely that I'll just close mine.
