What is a terminal voltage in a cell?

Terminal Voltage The most identifiable measure of a cell is the ‘terminal voltage’, which at first may seem too obvious to be so simple. In fact, the terminal voltage can change dramatically as a cell goes through charge and discharge cycles. The ‘nominal voltage’ is what the chemists tell us the cell should produce with zero current flowing.

What is the difference between deep discharge and terminal voltage?

Depth of Discharge (DOD) (%) – The percentage of battery capacity that has been discharged expressed as a percentage of maximum capacity. A discharge to at least 80 % DOD is referred to as a deep discharge. Terminal Voltage (V) – The voltage between the battery terminals with load applied.
