Abstract

An electrical battery according to the main patent has means provided to ensure a more rapid corrosion rate of the cup (7) in at least one chosen region in the lateral wall of the cup covered by a transparent zone (6) of the exterior envelope (5). The means may consist of reducing the thickness (8) of the cup's lateral wall in at least one area (8) the chosen region being this area. Several areas (8, 11) may be provided the thickness of the cup's lateral wall varying from one area to the other. The means may consist of at least one insulating piece, interposed between an area of the cup's lateral wall and the battery positive electrode (2). The region then consists of the periphery of the area.
