Charge retention

Latest updated: Jan 24, 2024

The ratio, usually expressed as a percentage, between the capacity that can be discharged from a battery after it has been fully charged under specified conditions, allowed to stand for a specified time at a specified temperature, and not recharged, and the nominal capacity of the battery.
