Isn't the voltage of a silver cell different than the voltage of a mercury battery? like, 1.5V vs 1.35V or so. Some meters designed to use mercury batteries are notably inaccurate when used with silver batteries (which in turn can be alleviated by re-calibrating the meter.) Can't remember which camera(s) was/were concerned, but neither Olympus OM nor Nikon if I remember correctly. More like rangefinders from the 70's.
The fix is called a C.R.I.S. adapter. About $35 from the original manufacturers, or $20 for a Chinese knock off. I have both, they both work fine. They regulate the voltage to down to 1.35v so everything works correctly.All the solutions are expensive and not good.
