Supercapacitor Technical Guide
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. The rate of discharge also changes as the voltage decreases.
Battery Charging and Discharging Parameters
Depth of Discharge. In many types of batteries, the full energy stored in the battery cannot be withdrawn (in other words, the battery cannot be fully discharged) without causing serious, and often irreparable damage to the battery. The Depth of Discharge (DOD) of a battery determines the fraction of power that can be withdrawn from the battery.
