Retention Capacity
Capacity retention is a measure of the ability of a battery to retain stored energy during an extended open-circuit rest period. Retained capacity is a function of the length of the rest period, the cell temperature during the rest period, and the previous history of the cell. Capacity retention is also affected by the design of the cell.
