Have a look at AAA's for a chuckle. If we compare them by mass, one
gets 4 times less in AAA's (2 cells) than in AA's (4 cells) for the
*same* price. The battery makers must be giggling all the way to the
bank over this one. Howver, my remote control doesn't care if it is a
fine vintage Union Carbide or a China special. That will have an
effect eventually, especially in lost jobs.

From a manufacturer's point of view AA and AAA probably cost about
the same. Small long tubes are harder to draw and fill without
rejects. What really annoys me is the way designers are pushing
toward AAA in LED flashlights and small portable radios to keep the
weight/size down. I would much rather have AA.
