#625 1.3 volt battery wein
Description I copied from Amazon:
"The zinc/air composition of the WeinCell delivers the same precise voltage with steady, constant output identical to that of the mercury batteries (alkaline replacements are generally 1.5 volts, with an unstable output curve; this can result in exposure errors of up to 2 stops)."
I did check the instruction book and mine uses the 1.3 volt battery; however I have been using the 1.5 volt battery for years.
