I've just recently started keeping an eye on the hacker website, Hackszine.com. There's a lot of good stuff on the site. This story was right on their front page.
This article just reminds us that A, AA, AAA, C and D batteries are all the same (1.5 volts), they are just different sizes. One thing I didn't know is that 9 volt batteries are also the same, they are made up of six 1.5 volt batteries (AAAAs) encased in a small box.
