@[email protected] when they stopped making things that used them. the newest thing around me that takes 9v is some Fischer Price walkie talkies, from '91 or so.
9v was always a weird voltage. isn't that like, half a "B" cell's voltage from tube radios? i know it's often used for bias voltage. also lots of audio amps want between 6 and 15v so they work great there so long as the current draw is low enough.
i needed AAAA (quad-A) batteries for an active touch stylus, and a pack of those was cheaper than a single 9v. however it is worth noting that a 9v battery can be constructed from 6x AAAA cells: http://www.bristolwatch.com/img/9volt.jpg
