A deep-cycle battery powering a traffic signal. 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 ...
Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached.

Wet cell stand-by (stationary) batteries designed for deep discharge are commonly used in large backup power supplies for telephone and computer centres, grid energy storage, and off-grid household electric power systems. [26] Lead–acid batteries are used in emergency lighting and to power sump pumps in case of power failure.
Zinc–bromine batteries share six advantages over lithium-ion storage systems: 100% depth of discharge capability on a daily basis. [3] Little capacity degradation, enabling 5000+ cycles; Low fire risk, since the electrolytes are non-flammable; No need for cooling systems; Low-cost and readily available battery materials
