Lead Calcium Batteries?
Just learned about Lead Calcium batteries. Found an add from a guy selling a set of them that were purchased in 1974 and says they are still working perfect and should last a lifetime. Obviously, I am sure there is a reason they are not widely distributed today, as far as I am aware, however I am interested to learn if anyone here has had any experience with this type of battery technology. I get excited when I here about a battery that will work for the rest of my life.!
