Vintage alternative to lead acid batteries
In the post war period, the ex government stores had rechargeable batteries for sale.
I cannot recall what they were called but had one electrode made of nickel and I think, a caustic soda ( v strongly alkaline ) electrolyte.
They had the advantage of being virtually indestructable with respect to over charging and short circuiting. Often sold made up in groups, within a wooden case giving 24 volts in total.
Anyone have info?
