Does anyone have an old No. 6 dry cell with threaded terminals that they can take a picture of how the negative terminal is attached to the can?
I have one with Fahnstock clips and it is soldered or perhaps spot welded to the outside of the can.
I presume the threaded kind are done in a similar fashion with a bracket that has the threads on it.
Usually can find old dry cells on eBay:
This listing has a good photo of the terminal:
Looks like a brass tab folded over the outside of the can. I would assume it was soldered.
Another example here. Looks like the tab is soldered so it points inward instead of outward:

No. 6 dry cells can still be bought. They're sold as starter batteries for model engines.
Here is a site for battery labels
I've finished the proto-type. The one on the left is the old one, the one on right the repro.
I have a Simms high-tension magneto that I plan to adapt to a T motor. This mag uses four No. 6 cells to intensify the spark at slow speeds. I couldn't abide using modern looking dry cells so I am attempting to make repros.
Those are the original A Type Batteries and they are still available for school lab projects and other applications.
AA and AAA Type Batteries are used more often now.
I remember using those many years ago to heat the glow plugs on my model airplane engines.
They are not as cheap as they used to be, but here is one source for the No. 6 replacement of the original A battery.
Jim - Very expensive for sure,....but then when you read the description of these "Air Alkaline" batteries, they are obviously much more high-tech modern than the old familiar "dry cell" batteries that we are used to.
