Capacity decay picture of lead-acid battery

Reversible capacity decay of positive electrodes in lead/acid

This chapter presents the types of lead/acid batteries for stationary applications, focusing on valve-regulated lead/acid (VRLA) designs. Batteries with capacities up to 200 Ah usually have flat positive plates; for higher capacities, tubular designs are also used. Lead/acid batteries were first used in stationary, stand-by applications more than 130 years ago. For a
