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.

The hearing aid cells are slightly thinner than the PX13. In some battery compartments, they don't make contact when stacked. I use them in my Gossen LunaSix and Nikon FtN meter prism, with 3 of the four holes blocked as described above.

OK, after using a light bulb to compare my QL17's meter to another QL17, four other SLR's, and five meters.. I am confused.
I will try again during daylight when I can use a grey card.

Use an evenly illuminated wall. If you use a grey card, be sure the meters and camera are close enough that you are metering off the grey card and nothing else.
