The white powdery substance is sulfuric acid and hydrogen crystals from the escaping hydrogen battery gases and liquid (the batteries have vents that allow the gases to escape.) This acid causes corosion of the copper wires and steel bolts attached to the battery and to some degree the battery posts and post connectors which are made of lead.
