the EdiRol SD-20, SD-80, SD-90, and E-MU Proteus 2000 series all don't have internal batteries thankfully, they use flash memory.
Yeap, there really isn't much at all inside of the SD-20 at least. I replaced the caps in mine late last year I believe it was. And with the exception of a few games or midi files, the SD-20 has just about replaced my MT-200 in terms of using it with games.
