Full discharge would result in both electrodes being covered with lead sulfate and water rather than sulfuric acid surrounding the electrodes.
How does lead sulfate react with sulfuric acid?
Lead dioxide and lead are discharged in sulfuric acid to form lead sulfate and water. The reaction reverses during charge, lead sulfate being decomposed to produce lead dioxide and lead. Both reactions take place via dissolution–precipitation processes.
