Open circuit voltage OCV -
The voltage of a cell or battery with no load attached measured with a voltmeter at room temperature.
Operating voltage -
Voltage between the two terminals of the battery with a load connected.
Over-charge -
Continuous charging of the battery after it reaches full charge. Generally overcharging will have a harmful influence on the performance of the battery which could lead to unsafe conditions. It should therefore be avoided.
Over-current -
Exceeding the manufacturer’s recommended maximum discharge current for a cell or battery.
Over-discharge -
Discharging a battery below the end voltage or cut-off voltage specified for the battery.
Oxidation -
The loss of electrons by a chemical species
