A standard 12 V car battery has an ampere-hour rating of 40 Ah, whereas a heavy-duty battery has a rating of 60 Ah. How would you compare the energy levels of each and the available current for starting purposes?

    Ah is a unit of charge.

    A battery with 12 V and charge capacity of 40 Ah will have energy content

    = volt x charge

    volt = 12 V

    Charge = 40 Ah

    = 40 x 60 x 60 A. s

    = 144000 coulomb

    energy content = 12 x 144000

    = 1728000 J

    energy content of heavy duty battery

    = 12 x 60 x 60 x 60

    = 2592000 J

    Ratio = 1728000 / 2592000

    = 2 / 3

    Current can not be compared as current depends upon the resistance of appliance used. As resistance of appliance is unknown, current can not be compared.
