Terminal Voltage (Vt) is the voltage between the battery terminals when a load is applied; this is typically lower than Voc. 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.

It notes the following regarding capacity-weighted average storage duration in megawatt hours (MWh): Batteries used for grid services only (stabilising the grid by discharging power for short periods of time) – 1.15MWh. Batteries used for electricity shifting only (shifting from times of low demand to times of high demand) – 4.15MWh.
In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A. Furthermore, if the battery is a 12V ...
