How to read battery discharge curves
Open Circuit Voltage (Voc) is the voltage between the battery terminals when there is no load on the battery. Cut-off Voltage (Vco) is the voltage at which the battery is specified to be fully discharged. While there is usually charge remaining, operation at voltages lower than Vco can damage the battery.
