The use of such an alloy at the positive post greatly reduces the rate of anodic corrosion.
A lead-acid battery comprising in combination a. a battery receptacle containing positive electrode, negative electrode and electrolyte; b. a cover for said receptacle in which there is at least one opening in said cover; c. a positive electrode post mounted within said receptacle and extending through said opening; and d. sealing means comprising epoxy seal for preventing leakage of electrolyte between said positive electrode post and said cover characterized in that the surface of the positive post to which the epoxy seal is made consists of lead-tin b...
