Well, unless you wanted to keep them as a museum exhibit, you could find
out by ripping the flat batteries apart to see how many cells they
contained (which I expect would have been ordinary 1.5 volt cells,
though of unusual shapes). I'd have thought they'd have the voltage
printed on them, though.

They didn't have anything printed on them. They were maybe 1.25" square
and 0.25" thick, and didn't look much like flashlight cells.

The dimensions are from a disassembly I did around the early 50's +- a
decade or so, and are not to be trusted.
