Abstract
A sealed lead-acid battery includes a separator made from hydrophilic treated sheet made from synthetic fiber which wraps at least either one of a positive electrode and a negative electrode. A mat type separator made from fine glass fiber is disposed between the wrapped electrode and its opposite electrode. This structure is adopted in a battery which uses a paste type electrode where an expanded grid having no outer frame on both edges is used, thereby prolonging cycle life even after cycling of charge and deep discharge.
