[Milsurplus] Duracell Coppertop battries

[John Vendely]

When still made by the original manufacturer, the P.R. Mallory Company, 
Duracell batteries were the highest quality.  Mallory invented several 
of the important dry battery types, including mercury and manganese 
types, and had numerous patents on alkaline types as well as battery 
case designs.  Mallory was a major supplier of batteries to the military 
from the 1930s on.  Duracell was probably the first long-life, 
leak-proof metal-clad battery sold as a consumer product.

P.R. Mallory was long ago dismembered and sold off, the Duracell trade 
name is now owned by the chinese, and what was once one of the very best 
batteries is now the worst...
