Abstract:

A method of assembling an electrical battery in which the container is used as part of the jig fixture wherein apertures are formed in the partitions separating the cells of the battery container. The plate groups are placed into each cell and a channel is formed adjacent the plates of like polarity in each plate group such that a part of each plate of like polarity is exposed in its respective channel. Molten metal is caused to flow only in the channels with the battery container in an upright position such that the molten metal flows through the apertures in the partitions to form inter-cell connectors between the respective battery cells and also to join the parts of like polarity in each cell. Compressive pressure is applied to the bus bars on opposing sides of the inter-cell connector to cause an expansion thereof and form a permanent seal where the inter-cell connector passes through each of the apertures in the battery cell partitions.
