Think about the example above of the difference between a light bulb and an AC unit. If you have a 5 kW, 10 kWh battery, you can only run your AC unit for two hours (4.8 kW 2 hours = 9.6 kWh). However, that same battery would be able to keep 20 lightbulbs on for two full days (0.012 kW 20 lightbulbs * 42 hours = 10 kWh).
In physics, energy density is the amount of energy stored in a given system or region of space per unit volume is sometimes confused with energy per unit mass which is properly called specific energy or gravimetric energy density.Often only the useful or extractable energy is measured, which is to say that inaccessible energy (such as rest mass …
