Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a VRLA configured to use as separators both a fine glass mat and a synthetic fiber nonwoven fabric processed into a bag shape, thereby reducing internal short circuits and extending the life compared to the prior art.SOLUTION: The VRLA uses a set of electrode plates including positive electrodes and negative electrodes opposed across separators. As the separators, both a fine glass mat and a synthetic fiber nonwoven fabric processed into a bag shape to enclose a positive electrode and/or a negative electrode are used. When X cmrefers to electrode plate area per positive electrode and Y μm refers to the median pore diameter of the synthetic fiber nonwoven fabric, 9.4≤X≤185.0 and -0.0796X+18.193≤Y≤-0.1856X+39.314 are simultaneously satisfied.
