Provided is a fluid-type lead storage battery wherein charging is performed intermittently for a short duration each time, and high-rate discharging to a load is performed in a partial state of charge, said lead storage battery improving the charge acceptance and the PSOC life characteristic relative to the prior art. A positive electrode plate is used that has a positive-electrode active substance total surface area per unit electrode plate group volume set in a range of between 3.5 and 15.6 m2/cm3. A negative electrode plate is used in which a carbonaceous conductive material and an organic compound that inhibits coarsening of a negative-electrode active substance accompanied by charging/discharging are added to the negative-electrode active substance. Moreover, compounds chosen from among cationic coagulant, cationic surfactant and phosphoric acid are added to an electrolyte, improving the charge acceptance and the life performance. |
