Battery Run Times Explained
Unfortunately this question does not have a clear simple answer. The easiest way to visualize is to compare a laptop and its battery to a car and its gas tank. In a car there are many factors that will determine your gas mileage; things like speed, driving habits, environmental conditions, amount of weight in the car, options, equipment, etc. A gas tank supplier can say that a tank holds 10 gallons, however they really cannot say exactly how fast a particular car will take to burn through that 10 gallons of gas. This problem eventually prompted the government to step in and mandate standardized mileage tests for cars.
