CONSTITUTION: In a lead acid storage battery, a negative electrode plate contains an organic expander having an S element content of 3,900 μmol/g or more and 6,000 μmol/g or less, and the ratio of a volume of an electrolyte to the total volume of positive and negative electrode plates is 1.1 or more and 3.0 or less.EFFECT: A lead acid storage battery is excellent in low-temperature high-rate discharge performance, and has low-rate discharge performance in a practical range.SELECTED DRAWING: Figure 2 |
