Voltage Depression - An abnormal drop in voltage below expected values during the discharge of a battery.
Discharge - The conversion of the chemical energy of a battery into electrical energy, and the withdrawal of the electrical energy into a load.
Open-Circuit Voltage (OCV) - The difference in potential between the terminals of a cell when the circuit is open (no-load condition).
Current Density - The current per unit active area of the surface of an electrode.
Tolerance in % - Limit for allowable variations for a given quantity, expressed as a percent of the rated value.
COS phi - A measure of the phase shift between the current wave and the voltage wave observed at the terminals of a load supplied with AC power at a given frequency.
Closed-Circuit Voltage (CCV) - The potential or voltage of a battery when it is discharging or charging.
