摘要： A cadmium-tin-lead alloy composition containing at least 0.4 percent by weight of both cadmium and tin is used for forming the straps employed which weld together the lugs of the grids in lead-acid storage batteries. The relatively small amount of cadmium and tin provide a large volume fraction of a cadmium-tin eutectic phase that is low melting and serves to facilitate the welding. This alloy composition may also be used to form intercell connectors and terminal posts for such batteries.

摘要： A maintenance-free battery having improved float current (i.e.-current draw) characteristics is provided by adding elemental zinc, or a zinc affording compound such as zinc sulfate to the battery in amounts sufficient to decrease the float current that would otherwise occur during voltage regulated overcharge. Rather than utilizing zinc alone, a mixture of zinc and cadmium may likewise be employed.
