Downwardly extending members are molded on the inside of a synthetic resin battery case cover and bear against the bridging members of battery plate assemblies or upward bulges of the battery plates to hold the latter vertically in place. The downwardly extending thermoplastic members may be heat-softened at their ends at the time the cover is fused onto the rest of the battery case, or they may be made so that they will flex at that time or they may be made of two members that will telescope together against strong pressure, so that they will still bear against the electrode plates after the cover has been fused onto the rest of the casing. |
