Challenges from corrosion-resistant grid alloys in lead acid …

This has lead to the use of 0.02–0.05% calcium alloys for corrosion-resistant grids. Lead–calcium alloys have been shown to require some tin to adequately recover from deep discharge. The minimum tin content has been shown by Giess to be about 0.6% tin [12]. Many of the corrosion-resistant grid alloys contain 0.5–0.7% tin.
