Abstract
A lead acid battery of the present invention has: an electrode plate pack including a plurality of negative electrode plates which each comprise a negative electrode grid having a tab and a negative electrode active material layer retained by the negative electrode grid, a plurality of positive electrode plates which each comprise a positive electrode grid having a tab and a positive electrode active material layer retained by the positive electrode grid, and a plurality of separators separating the positive and negative electrode plates; a positive electrode connecting member connected to each positive electrode plate of the electrode plate pack; and a negative electrode connecting member connected to each negative electrode plate of the electrode plate pack. The positive electrode grid has a lead alloy layer including 0.01 to 0.2 parts by weight of Sb per 100 parts by weight of the positive electrode active material on at least a part of the surface thereof where the positive electrode active material layer is in contact. The negative electrode active material layer includes 0.0001 to 0.003 parts by weight of Sb per 100 parts by weight of the negative electrode active material.
