Why does my portable stereo require 6 x type C 1.5V batteries... when they
could simply have designed it to accept a square 9V battery?

Any explanation?

It's called capacity: those 9 V batteries have tiny cells (6 of them in
series), each cell ~1/20 (or even less) of a type C cell.
Those 9 V batteries are ~1/2 the price of 6 type C batteries, so the end
result is very expensive proposition: you'll have to replace them very
often.

To put it into more exact numbers, a Duracell C-size alkaline is about
7100maH, and a Duracell 9-volt alkaline is about 600 maH. When you put the
C-size batteries in series to get 9 volts, it's still 7100maH at 9 volts
instead of 1.5 volts. So 7100maH / 600maH is 11.83 times the power. So for
every set of C-size batteries, you'd go though about a dozen 9-volt
batteries.

I agree! This has been bugging me for ages. I guess I should just learn
more physics.
