The Nominal Capacity of the battery is given at this C-rate. The discharge current can then be worked out from the C-rate and the Nominal Capacity. For example if a battery has a C1 capacity of 400Ah, this means that when the battery is discharged in 1 hour, it has a capacity of 400Ah.
Nominal capacity is a standardized measure often provided by manufacturers. It is determined under specific conditions, such as a fixed discharge rate over a set period (commonly 10 or 20 hours). The nominal capacity allows for easier comparison between different battery models and brands.
So if a battery has a nominal capacity of 500Ah and a nominal voltage of 12V, the overall nominal capacity in kWh is 500 * 12 = 6,000Wh, or 6kWh. Remember the battery only has this capacity when operating at the nominal discharge current … The power output of the battery in Watts is given by Discharge current (A)* Voltage (V)
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
It is important to distinguish between the nominal capacity of the battery and the usable capacity of the battery, expressed as nominal capacity * maximum Depth of Discharge. Typically for lead acid batteries, the usable capacity = 50% of the nominal capacity.
Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).
