Beschreibung
Zusammenfassung:	A long-life, high-reliability, closed lead acid storage battery in which the electrolyte is hardly layered. (1) A closed lead acid storage battery comprising an electrode plate group including a positive electrode plate, a negative electrode plate, and a separator which is formed mainly of glass fibers and to which a silica powder is mixed is characterized by assembling the electrode plate group with a compression pressure of 60 kpa or more and by inserting the electrode plate group into the jar. (2) A closed lead acid storage battery comprising an electrode plate group including a positive electrode plate, a negative electrode plate, and a separator which is formed mainly of glass fibers and to which a silica powder is mixed is characterized in that the filling rate of the electrolyte with respect to the electrode plate group total void volume is 92% or less. Alternatively a closed lead acid storage battery is characterized by a combination of (1) and (2).
