A lead–acid battery has two main characteristics: the thermodynamic equilibrium voltage U0 and the complex battery impedance. These characteristics are represented in a basic Electrical Equivalent Circuit (EEC). When a discharge (load) or charge current flows through the terminals, voltage drops (overvoltages) across the impedance terms are added to U0.
The lead–acid system is thermodynamically unstable. The two most relevant side-reactions for commercial batteries are corrosion of the positive current-collector (highlighted) and electrolysis of water (highlighted). In valve-regulated lead–acid batteries (VRLA), recombination of oxygen is also a relevant process influencing the potentials at both electrodes.
