Zusammenfassung: | The present invention relates to a packed battery unifying a plurality of battery cells (A) housed in a case (1). The case comprises a tubular body housing (10) the battery cells (A) and a couple of lids (2,3) closing both the end openings of the tubular body respectively, thus being arranged in a three-unit construction. This arrangement allows the case to be completely sealed off by ultrasonic wave welding. |
