I got an old Seiko requiring the RW56 RayoVac battery. These were discontinued as they contained Mercury.
The data is the following:
11.6mm X 3.6mm 1.35V LM
Most batterys listed as replacements are 1.55V while the original was 1.35V. Would it be a bad idea to put a 1.55V battery into a Seiko requiring a 1.35V battery?
Anyone have a good suggestion of a replacement?
I think I might be able to find a Zinc-Air battery with the same data. Are these the only replacements?
