Kodak Alkaline Battery

[Kirk]

Hello!
I have a Kodak Alkaline "D" battery, model LR20, made in USA for Kodak. The (-) end looks like a typical D battery with the concentric rings stamped in the metal. The (+) end is totally flat like the old-style cheapie import batteries. Anybody know why there is no button on the (+) end? These came in an antique French "artillery sighting set" my wife got me for Christmas from Deutsche Optik, I believe.
Regards,
Kirk

What you have sounds like a flat-top cell. These are common with rechargeable cells for use in packs, but I've never seen flat-top Alkaline D cells.

I would make sure that button-top D cells will fit in place of the flat-top cells, as they are typically slightly longer including the length of the button.

Just did a quick google search and found the + and - are reversed! This may or may not be important.

gwbaltzell,
Thanks for the link. Now, if both ends are flat, why would it matter if the + and - are reversed? And, how would a person know except by looking at the side of the battery case? Also, what is the purpose? I can see all sorts of problems arising from reversing a couple of cells if you're in a hurry!
