A plurality of batteries (1) are stacked, together with spacers (18), in a compressed state. Charging and discharging units (22) are arranged facing lead terminals (2, 3) protruding from the batteries (1) and are independently operable for the respective batteries (1). The charging and discharging units (22) each independently include substantially V-like shaped power-side and measurement-side contact elements (23, 24) elastically supported by compression coil springs (28) and having floating freedom. When the batteries (1) are moved all together toward the charging and discharging units (22), front end surfaces (e) of the lead terminals (2, 3) are pressed against and electrically connected to flat surfaces (35) of the power-side and measurement-side contact elements (23, 24). By this, it is possible to smoothly perform charging and discharging inspection on the batteries (1) even when the lead terminals (2, 3) protruding from the battery package are subjected in advance to surface treatment. |
