Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sealed type lead-acid battery in which the stratification of an electrolytic solution is hard to occur, and which has a long life and is highly reliable. SOLUTION: (1) In the sealed type lead-acid battery which is provided with an electrode plate group composed of a positive electrode plate, a negative electrode plate, and a separator which has glass fibers as a main body and has mixed silica powder, the electrode plate group is assembled so that a compression force is 60 kpa or larger and the group is inserted into an electrical container. (2) In the sealed type lead-acid battery, the filling rate of the electrolytic solution as opposed to the total hole volume of the electrode plate group is made to be 92% or less. Or, (1) and (2) are combined. COPYRIGHT: (C)2005,JPO&NCIPI
