The cells are arranged side by side with adjacent short lateral walls that are integral with each other. Upper open ends of the cell cases are integrally closed with a single lid member.

Abstract: A battery module includes a plurality of cells accommodating an electrode plate group and an electrolyte, and a single integrated battery case for accommodating the plurality of cells. The ratio of the component resistance including the connecting resistance between the cells to the reactive resistance of the electrode plate group and the electrolyte in each cell, is set in the range of 1:99-40:60 at a temperature of 25° C. Thereby, the internal resistance per cell is reduced, and higher power output and improved service life characteristics are achieved.

Abstract: A mail wrapping system apparatus for preparing for mailing postal items includes receiving trays for respectively receiving postal items from companies and an extraction device for extracting from the postal items a multiplicity of same address groups of the postal items, each of the same address groups consisting of ones of the postal items having coinciding ones of destination addresses. A wrapping unit respectively individually assembles each of the same address groups into a bundle and successively wraps each of the same address groups assembled using a wrapping component with a corresponding one of the destination addresses respectively displayed on each of the wrapped same address groups to provide for mailing the wrapped same address groups. A weight sorter then sorts the wrapped same address groups into weight divisions set forth by a fee schedule of a specified delivery agency and the wrapped same address groups are sent with appropriate postage.

Abstract: A sealed lead-acid battery includes a separator made from hydrophilic treated sheet made from synthetic fiber wraps at least either one of positive electrode and negative electrode, and 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.

Abstract: An alkaline storage battery having excellent self-discharge characteristics even after a number of charge-discharge cycles is provided. The alkaline storage battery is provided with a case and an electrode group enclosed in the case, and a separator that is included in the electrode group retains at least 15 mg/cm2 of an electrolyte at least in a period after assembling the battery, from the time the separator is impregnated with the electrolyte to the time the battery is activated.

Abstract: A rectangular alkaline storage battery includes a plurality of rectangular positive electrode plates, negative electrode plates, and separators. The positive and negative electrode plates are layered alternately via the separators, resulting in a group of electrode plates. The group of electrode plates, together with an alkaline electrolyte, is housed in a rectangular container. In the battery, internal resistance is 5 m&OHgr; or less, the electrode plate group thickness is 30 mm or less, and the amount of electrolyte is 1.3 to 8.0 g/Ah. This can achieve a rectangular alkaline storage battery that provides the optimum balance in the quantity of heat generation, heat release, and heat accumulation, high power, and excellent battery characteristics even when charged/discharged repeatedly and used for a long time.
