“Self discharge and leakage current are essentially the same
Leakage current: The small amount of additional current that is required, during charging the Supercapacitor to maintain the charge on the capacitor .
Self-discharge: The small amount of current that will discharge the Supercapacitor when the charge voltage is removed, and the capacitor is not loaded.
Inflow current: is a combination of charge current of the dielectric absorption elements and leakage current. In order to get a realistic measurement of leakage or self discharge current the Supercapacitor must be charged for in excess of 100 hours.”
