Rated Energy Storage Capacity is the total amount of stored energy in kilowatt-hours (KWh) or megawatt-hours (MWh). Capacity expressed in ampere-hours (100Ah@12V for example). The amount of time storage can discharge at its power capacity before exhausting its battery energy storage capacity.
Battery Energy Storage Systems (BESS) are essential components in modern energy infrastructure, particularly for integrating renewable energy sources and enhancing grid stability.
For example, if a fully charged battery with a capacity of 100 kWh is discharged at 50 kW, the process takes two hours, and the C-rate is 0.5C or C/2. As a specification of a battery, the C-rate usually indicates the maximum C-rate, meaning that the higher this key figure, the faster the battery can be charged and discharged.

This is the energy that a battery can release after it has been stored. Capacity is typically measured in watt-hours (Wh), unit prefixes like kilo (1 kWh = 1000 Wh) or mega (1 MWh = 1,000,000 Wh) are added according to the scale. The capability of a battery is the rate at which it can release stored energy.
