Formation & Aging
Aging. After the formation process, the battery goes through a period of aging, which involves repeated cycles at different rates and rest times. The purpose of aging is to stabilize the battery''s electrochemical performance and make its voltage more accurate. Aging can be done at room temperature or at a higher temperature. Cost and Energy
Battery Degradation and Ageing
Maintenance of batteries is necessary to ensure good performance, e.g. complete discharge of nickel - cadmium batteries to avoid capacity loss due to the ''memory effect'' or routine charging of lead - acid batteries to avoid capacity loss in storage due to sulphation (formation of unreactive lead sulphate in the battery plates).
