Abstract
Abstract Apparatus for acid-filling and forming of storage batteries has a frame which is arranged to hole several storage batteries (30) simultaneously. In the frame a duct system (18-25) is in direct contact with the cells (35) of each storage battery (30) fixed in the frame. The duct system supplies acid simultaneously into each storage battery (30) and a circuit (13) simultaneously supplies charging current to the terminals of each storage battery with the electrical interconnection between the terminals of each battery (30) and the circuit (13) being made by installing the respective battery (30) within the frame.
