I own a Spotmatic F - I found a vendor on eBay that sells an exact replacement for the original PX625 mercury battery which the Spotmatic F required
This replacement is a 1.35 volt WeinCell MRB625 battery. sold on eBay by
1111deals, costs: $5.91 with free shipping
type this into eBay search to pull up this listing: WEINCELL W990120 Replacement Battery for PX625/PX13
You should be able to do a web search for WeinCell MRB625 and find other vendors.
With this exact spec replacement you won't have to worry about any over-voltage issues and your meter should work correctly - pending any CLA required
All the best,
Pierre

I have a Spotmatic F that has a light meter that does not function properly on certain LR44 1.5v batteries and works inaccurately on some, i can say that this Spottie F is picky. what i do is I confirm the proper exposure with my other Spottie F that i use more often and see a discrepancy between their measures having the same light conditions.
I experimented on using a 3v CR1616 battery that i had and the light meter worked much responsively.
Are there any hazards on using a battery half over the recommended volts?
