Yes, they would not be suitable for automatic shutter cameras like the
OM-2 and 4 series. They held very stable voltages with great shelf life,
but were not suitable for high drain surges. They only had to run a
simple lightmeter in the OM-1n. Given the time frame of development, I'm
pretty sure it was theses characterstics, rather than thoughts of
mercury contamination that led to the change to silver oxide batteries
for the OM-2
