PURPOSE:To provide a sealed lead-acid battery with a long life property. CONSTITUTION:Regarding a sealed lead-acid battery in which the theoretical capacity (Ah) of the whole negative electrode active materials is lower than the theoretical capacity (Ah) of the whole positive electrode active materials, the addition amount of a conductive additive such as carbon, etc., added to the negative electrode active materials is set to be at least 0.4wt.% and at heightest 7.5wt.% of the mass quantity of the negative electrode active materials. |
