Abstract:
A lead acid storage battery including: positive electrode plates each including a positive electrode grid and a positive electrode active material, and negative electrode plates each including a negative electrode grid and a negative electrode active material. The positive and negative electrode plates are stacked alternately with a separator therebetween to form an electrode plate group. The battery further includes: a battery container having cell chambers each containing the electrode plate group and electrolyte, and a cover sealing an opening of the battery container. The positive electrode active material has a pore distribution having a peak in region A from 0.03 μm to 0.1 μm and a peak in region B from 0.2 μm to 1.0 μm, and a ratio AM/BM of peak AM in region A to peak BM in region B is 0.34 or more and 0.70 or less. The negative electrode grid contains bismuth in an amount of 1 ppm or more and 300 ppm or less.

Claim (Index 2):
The lead acid storage battery of  claim 1 , wherein at least the positive electrode plate is provided on a surface thereof with a retainer mat.
