A cover for a storage battery adapted to contain an electrolyte in at least two cells provided side by side, and a method of making such a cover and a battery comprising such a cover, said cover comprising channels (3) in order to convey gas being developed in the cells (5) to the exterior of the battery through a common outlet. Said channels are formed in the top of the cover, and are defined by walls (6) which protrude perpendicularly to the top of the cover, and in partition walls (9) in the cover, adapted to form partitions between the cells (5) in co-operation with partition walls in a battery box, are apertures which make adjacent cells communicate with each other through said channels (3), and at least one cell communicates with the surroundings. The channels (3), which can be shaped like labyrinths, are cast as open channels in the top of the cover, whereupon a channel bottom is formed or fastened subsequently to the casting, preferably by melting together the edges (7) and the cast walls (6) of the channels (3), said melting being preferably performed simultaneously with the melting together of the cover and a battery box. |
