Video teaches you battery basics
My old MAKE colleague Collin Cunningham made an entertaining and educational video that explains battery specs: milliamp hours, voltage, chemistry type, etc. I've never opened a 9-volt battery but Collin did, and he shows you what's inside: six little 1.5 batteries wired in series. Collin also makes the music for all his videos.
