Drop-in replacement for older mercury-containing batteries
I have a couple of older, 70s era photography devices (a light meter and a 35 mm camera) that used the now unavailable PX-13/PX-625/MR-9 batteries, which were very good batteries but their mercury content forced their discontinuation. These older batteries had a fairly unusual voltage, 1.35 V, (and shape) so it isn't easy to find a simple, straightforward substitute. This WEIN cell is a direct, drop-in replacement and works well. These are referred to as "zinc-air' batteries and if stored unactivated have a long shelf life. Once activated they apparently will be usable for about a year.
There is apparently a more expensive solution that involves an adaptor that can then be used with a specific silver oxide cell and together they will duplicate the PX-13 batteries; some people may find that approach to be more economical in the long run.
