Try four AA NiCd batteries. Nominal voltage will be 4.8V; the package will end up about 1"x1"x2". AAs are usually about 450mAH; the "9V" cells are about 75maH as I recall. If you take apart the generic "9V" you will find 6 small cylindrical cells. Cutting the connection and using four removes the need for the dropping diode. You still end up with a lame battery. The newer 8.4V batteries use a stack of flat cells specially designed for the "9V" application rather than the cylinder sort which seem to be Q&D adaptations of the AA, cut off at the knees.
