Because what is in a 9 volt is 6 AAAA batteries. They are smaller than even an AAA battery. Only thing I know that uses them is some of the surface drawing pens and the like.
That said if you need 9 volts ask a church. I know we would gladly hand you a box of half full ones as you have to pull them out of the wireless mics before they die. And older Shure mics are 9 volt.
