An electrode plate (Ib) for a lead acid battery comprises an electrode material supported on a metal support in which the metal support comprises a body portion and a tab portion (4c) which extends from the periphery of the body portion. The body portion comprises a region of grid (2b) and a conduction rail (3c, 3d) which has at its widest part a width of at least 5 mm and which extends in a direction generally parallel to the direction in which the tab portion (4c) extends from the periphery of the body portion. Preferably, the metal support comprises two conduction rails (3c, 3d) which are tapered in opposite directions.
