It is Mouser's part #614-CR2032FH-MFR, Manufacturer Part #CR2032FH MFR, and can be bought for $1.43 from www.mouser.com. I was going to go with the socket approach on my Yamaha DMP-11, but could not find one that I felt would fit well enough to suit me. I ordered 3 batteries and had them in four days. Now my DMP-11 is happy again!. But shame on Yamaha for not allowing for an easier way to change these!

The symptoms/issues is that playing a performance, each time I would hit a key, it would cycle through each of the 8 parts. In-other-words, if you have "Full Tines" on the 1st voice and all 8 parts are on (although only part 1 has a voice assigned), playing the keyboard will play part one, pressing keyboard keys again then plays part 2, 3, 4, 5, 6, 7, 8, and then finally plays 1 again!!! Weird. Unfortunately the battery change over was not so easy. Had to take the entire circuit board out and un-solder the original batter (which is permanently affixed to the clip/holder). I then soldered a wire, one each into the Positive and Negative. Haven't had a chance to find a newe "clip" so I soldered the wires straight into the new CR3205(? I think that's what it was) and wrapped it really good not to cause a short. That baby works fine now!!!!!!
