Self-discharge is the rate of voltage decline when the capacitor is not connected to any circuit. The rate of self-discharge is dependent on the state of charge it was held out before being disconnected from the circuit. A part that is quickly charged then left to sit will discharge faster than one that is held on charge for many hours.
