Abstract
A method for preparing plates primarily intended for use in a dry charge battery includes washing pasted and formed battery plates in water flowing at a low flow rate until most, but not all, of the forming acid has been removed, and thereafter washing said plates in additional water flowing at a higher flow rate to remove residual acid; treating the additional wash water using an ion exchange bed to remove the acid and reusing the deacidified water as wash water.
