Zusammenfassung:	An electric storage battery grid made from an improved low antimonial content lead alloy is disclosed. The battery grid can be used to manufacture maintenance free lead acid storage batteries. The alloy has an improved combination of low gassing rate and hardness, castability and pasteability and contains less than 2.0%, i.e. approximately 1.3 to 1.9 weight percent antimony, 0.05 to 0.45 percent arsenic and 0.02 to 0.5 weight percent tin as well as small amounts of copper and sulfur.
