My Konica Autoreflex TC uses 2 batteries, Stacking them blocked the air holes and I didn't get a current. I ended up buying 2 adapters so I can use the hearing aid cells. All the adapter is, is a cleaned out alkaline px13, which leaves a hole for the hearing aid cell. It works very well in my Konica. Why did I buy the adapter? Because I don't want to mess with the chemicals in the battery, it was worth it to me to buy them already cleaned out.
