Hah!. Maybe I had the last one which arrived today. You can also use 4 off PC640A batteries but looks like SBC is out of them as well. Worth tracking down the A32PX if you can as they do last for years.
Problem with the other options is they don't supply sufficient current so the battery check light may not work and the exposure lights may be dim. But the camera will, usually, expose correctly as it's very tolerant of battery voltage. I did a comparison some time ago. Details at http://www.contax139.co.uk/yashica-electro-35-batteries
