Hi all. First time post here so forgive me if this is noob-ish.

I acquired a Fujica Zoom Deluxe 8mm camera, and decided to put in some fresh batteries. The double-A batteries fit fine in the slots the manual recommends for "1.5 volt penlight batteries". BUT--I want to replace the battery for the "electric eye exposure control" (light meter.

The manual says I need a "2.6 volt mercury battery". I know that these guys are no longer available (right?). So... what do I do? Thanks!

Find a local camera shop or a Batteries Plus, they should be able to help you out.

The technology mostly used to replace Mercury cells is Wien cells (I think zinc/air) and this is what your local camera shop is most likely to have.
These are quite expensive as batteries and don't last as long (in my experience less than a year).
You'd think in these modern times someone would have made an economical cell that would be at least a match for the archaic mercury cells in terms of performance and consistency.

Thanks. I see the Wein batteries are widely available. The issue is how to put them together to equal 2.6 volts (all of them appear to be 1.35 volts). I can put two together, but doesn't that require some sort of adapter or spacing or something?

I would just forego the battery replacement for the light meter and use a handheld light meter. But it appears that I can't see what f-stop the camera lens is at without the light meter! Not the best design, I think.

So, anyone know how whether there's a trick or something to putting together two of these: http://www.bhphotovideo.com/c/product/96457-REG/Wein_W9901201_MRB625_Cell_1_35v_Zinc_Air.html

for a 2.6 volt mercury batter replacement?

(People at Batteries Plus seem not to have such batteries, so I don't know if they'd know.) Thanks for any help.

I will have to scratch my head on this one then. The Batteries Plus commercials say something to the effect if they don't have it, they will get it or build it....did you lay it on their desk in person or just look over their site?

you could try this site they said a Similarly, the A14PX alkaline battery, which replaces the PX14 mercury battery, operates at 3 volts while the original operated at 2.7 volts. Again, this battery is compatible with the devices that take the PX14 mercury battery despite the voltage difference. This battery is also used in many older cameras.

also on ebay too

the battery i have from my old super 8 camera is still new i just checked it and it has 2.69 volts in it and its a mercury one made in germany.
