Making Odd Sized Batteries by Nokton48, on Flickr

I just unearthed these two Calumet Flash Meters in my studio, and I'd like to get them going again. Thirty years ago I went to Batteries Plus, and they built these custom batteries for me, which worked great! Inside the cardboard tube is four Number 344 batteries, soldered together with tabs. I called Batteries Plus and they really don't do stuff like this anymore.

I think I can get 344's or equivalent, where do I get the soldering tabs? I can do the work and I really see no need to pay someone to do this. Any tricks from you Guys out there to constructing these Odd Sized Batteries?

The 344 1.55V looks like a standard watch battery, easy to get. Can prolly get them at the local grocery store
