Abstract: A method of testing a secondary battery includes first to fourth steps. At the first step, the secondary battery after manufacture is charged to a first voltage. At the second step, a second voltage lower than the first voltage is set as a target voltage and discharge or charge is performed in a constant-current constant-voltage mode before the secondary battery is left standing. At the third step, the open circuit voltage of the secondary battery is measured before and after the secondary battery is left standing. At the fourth step, it is determined whether the secondary battery is a conforming item or not based on the difference in the open circuit voltage before and after the secondary battery is left standing.

Abstract: To melt and diffuse metallic foreign bodies immixed in electrodes of a nonaqueous electrolyte secondary battery before initial charging, electrodes (18) wound with a separator (24) between a cathode plate (20) and an anode plate (22) are placed in a battery case (16) and the battery case (16) is filled with an electrolyte. After the case has been filled, the electrolyte is allowed to permeate into the electrodes (S14). Then, the electrolyte-filled battery (14) is placed in a processing device (10), and fixed by means of a surface pressure between at least 0.1 MPa and 5.0 MPa (S16). Thereafter, the cathode potential is adjusted and held for a period of one hour and 35 hours (S18) while the battery remains fixed, after which the pre-initial charging process is terminated (S20).

Abstract: A differential device includes a differential case which is supported in a housing so as to be rotatable around an axis of the housing by a conical roller bearing including plural conical rollers provided between an outer race and an inner race. In the differential device, a wave spring having a predetermined elastic force is provided between the outer race and the housing. Also, the differential device includes a stopper mechanism which stops movement of the outer race before the wave spring is completely contracted due to movement of the outer race in an axial direction.
