A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or ''cranking'' automotive batteries designed to deliver only a small part of their capacity in a short, high-current burst for cranking the engine.
