    I landed an older Spotmatic (Honeywell/US import) and need to get a batery
    for the meter. I'm assuming the original mercury types ar no longer
    available, but what--if any--modern-day alkalines can I use in it's place?

    Another option if you desire to maintain the 1.35v, other than the seemingly
    unpredictable zinc-air batteries, is the C.R.I.S. adaptor: I believe the H-B is dedicated to the
    pentax. But, one might as well try the silver-oxide batteries by themselves
    to begin with.

    Older spotmatics like those branded for Honeywell import
    used a bridge circuit and were voltage-insensitive.
    You can use 1.5v relibly in them. Only later units
    like the ES were sensitive to voltage.
