Purpose It is a purpose of the present invention to provide a lead-acid battery for use in idle reduction operation in which both excellent life characteristics and suppression of corrosion of negative-electrode grid ears are achieved by suppressing variations in SOC between cells. The fixing apparatus includes a support board, a rotating member rotatably mounted to the support board, a moving member, and a number of positioning members. Bonding of the locked-in ply with the inboard and outboard results in improved structural performance and damage tolerance. The retrieved data may be translated from the plurality of tables of the relational database into a format for output to the spreadsheet application. The internal threading of the first jam nut may be configured to mate with the external threading of the first extension rod to tighten the first jam nut against the first end of the elongated body so that the skirt of the first jam nut is positionable about the first end of the elongated body. The second transistor can generate higher first bias currents during higher load currents, and the voltage-to-current converter can generate higher second bias currents during faster load current variations.
