[sdiy] OT: DX7II Battery?

[Grant Richter]

Use the CR2032 socket from Radio Shack. You only need to solder one of the
20mm terminals as current is nonexistent. Cut off the other terminal and
insulate and reinforce with silicone bathtub caulk (RTV).

Have used this technique on all 8 sections of a TX-816 (rack mount DX7).
