What: "Say we compare a digital camera to a car - the energy capacity is your fuel tank capacity so how far your car can travel depends on the capacity of your fuel tank and similarly, how many shots you can take with the battery depends on the battery's energy capacity. The power density is like the torque or "pick-up power" of your car. If you sit ten big fat people in your car and still manage to accelerate from 0 to 100MPH in 8 seconds then you would say the car or fuel has good "pick-up". So when your camera demands high power in a short moment like just as when a picture is taken and if the battery can deliver it instantly without any complaint then it is said that the battery has high power density."
