Hello Everyone,
This is my first post here, but I've been a lurker for a while; thank you guys for all the awesome information on here.
I just wanted to share this awesome battery I found recently online. I was looking for antique batteries that would show well with some antique flashlights that I just bought and came across this unique battery. It is a Columbia Dry Cell No. 4 that is looks great for its age. I can't seem to find any information on this battery, which seems similar to a no. 6 Columbia dry cell. I believe this battery is from the 1890's or very early 1900's, as I have looked at every no. 6 battery image I could find from 1904 until the merger of National Carbon, and they all display a different eagle logo than the one on my battery. Plus, it has a patent date of April 13th, 1893. But the awesome thing about this battery is that it still somehow holds a charge! I tested it with my multimeter and it seems to hold steady at about 1.02 volts! If I let it "recuperate" like it says on the label, I can get the meter to spike at 1.05 volts before it falls back back to 1.02 volts. I just find it amazing that a battery this old can hold a charge for so long, all while not leaking. I have linked images of it below so I don't crowd up this post, the only issue with it that I can see is a tiny bit of corrosion on both screw terminals.
