Aging mechanisms and service life of lead–acid batteries
The lead–acid battery is an old system, and its aging processes have been thoroughly investigated. This "thermodynamic" over-voltage for hydrogen evolution at the lead electrode increases with acid concentration, Role of hydration water in the reduction process of PbO 2 in lead–acid cells. J. Power Sources, 64 (1997), pp. 57-60.

The chemical reactions are again involved during the discharge of a lead–acid battery. When the loads are bound across the electrodes, the sulfuric acid splits again into two parts, such as positive 2H + ions and negative SO 4 ions. With the PbO 2 anode, the hydrogen ions react and form PbO and H 2 O water. The PbO begins to react with H 2 SO 4 and
