Voigtlander VF 135 battery?

I have just bought a Voigtlander VF 135, but have yet to receive it. I understand that this camera should have a mercury battery which are now discontinued. Which is the best viable alternative.if any!

Several alternatives:

1) There is a Wein-brand battery that is the same size and shape as the original PX13/625 mercury cell. I find these to be a bit expensive.

2) You can get one of those battery adapters that allow you to use a silver oxide S76/LR44/365 cell. They're a bit expensive -- about US$25, not including the battery.

3) You can use hearing aid batteries, sometimes with a rubber "O" ring from the plumbing area of a hardware store. I think the #9 ring works. You can usually buy a 10-pack of the hearing aid batteries for about US$10, and each lasts about six months.

I'll have to check the battery chamber at home, but I think that a hearing aid battery should be sufficient. Sometimes, these batteries aren't tall enough, and adding a metal washer to fill the gap almost always works.

Varta make an alkline battery - V625U which slips right in, i use these in a minolta sr7 , does the job but not long lasting. regards

I just checked. One contact point is on the bottom. The other is on the side.

What I did with my camera was to cut the "O" ring so it would go around the side contact point.

It works well.

Many thanks Mike and Pakeha for the advice. Very much appreciated.
