Deep cycling, which involves repeatedly discharging a lead-acid battery to a high depth of discharge (DOD), significantly reduces its lifespan. The depth of discharge refers to the percentage of the battery's capacity that is discharged during a cycle. High DOD means a large percentage of the battery's stored energy is used before recharging. Deep cycling accelerates several degradation mechanisms within lead-acid batteries. One primary mechanism is the shedding of active material from the positive electrode (lead dioxi....
