Usable storage capacity is listed in kilowatt-hours (kWh) since it represents using a certain power of electricity (kW) over a certain amount of time (hours). To put this into practice, if your battery has 10 kWh of usable storage capacity, you can either use 5 kilowatts of power for 2 hours (5 kW * 2 hours = 10 kWh) or 1 kW for 10 hours.
Usable storage capacity is listed in kilowatt-hours (kWh) since it represents using a certain amount of electricity (kW) over a certain amount of time (hours).
