Need a battery for you Yashica Electro? Yashica Guy makes an adapter so you can use modern batteries in your Electro-camera. I guess in the long run, it’s easier then to try to find replacements.
For my Yashica Minister D I found the right batteries (PX 625) in a swedish officeshop, I think they also used this model to calculators and stuff.
Oh, and for Yashica owners I added this page to the links the other day.
