Introduction The lead–acid battery is an old system, and its aging processes have been thoroughly investigated.
Lead-acid batteries are sensitive not only to overcharging and overdischarging but also to chronic undercharging: if not fully charged, aharmful build-up of sulphate crystals on the electrodes in a process called sulphation raises the battery internal resistance.
