Abstract
A method for manufacturing lead plates for a lead/acid battery includes the step of providing lead electrode grates and filling an active paste into the lead electrode grates to form filled lead plates. Subsequently the lateral surfaces of the filled lead plates are subjected to a continuous processing sequence of less than 6 hours under preselected processing parameters for time, temperature, humidity, and air movement. The processing sequence includes a curing step in which moisture is added to reach a first humidity value, a predrying step for reducing the amount of free lead in the active paste at a second humidity value that is lower than the first humidity value, and a final drying step.
