Regarding hydrogen evolution, one must consider that the potential of the reversible Pb/PbSO 4 electrode is 0.3–0.4 V below the potential of a reversible hydrogen electrode in the same solution. This "thermodynamic" over-voltage for hydrogen evolution at the lead electrode increases with acid concentration, as illustrated by Fig. 8.

5 Lead Acid Batteries. 5.1 Introduction. Lead acid batteries are the most commonly used type of battery in photovoltaic systems. Although lead acid batteries have a low energy density, only moderate efficiency and high maintenance requirements, they also have a long lifetime and low costs compared to other battery types.
Operation of Lead Acid Batteries
In practice, however, discharging stops at the cutoff voltage, long before this point. The battery should not, therefore, be discharged below this voltage. In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery''s state of ...

Lead-acid batteries and lead–carbon hybrid systems: A review
However, adding carbon encourages hydrogen evolution in the dilute sulfuric acid medium compared to lead due to its lower hydrogen overpotential. The HER, a kinetically hindered reaction, generally occurs near the end of charge or during overcharge, resulting in increased internal pressure in the cell and loss of water.
Lead-Acid Battery Basics
The voltage of a typical single lead-acid cell is ∼ 2 V. As the battery discharges, lead sulfate (PbSO 4) is deposited on each electrode, reducing the area available for the reactions. Near the fully discharged state (see Figure 3), cell voltage drops, and internal resistance increases.
