        compare a car battery thats lead based and heavy and not rechargeable, to the one in your cellphone that is more powerful and way thinner and safer.

            The battery starts the car and then the alternator charges the battery.

          By what measurement is a car battery, at something like 75,000mAh and 500 or more cranking amps, less powerful than a cell phone battery?
