    Dear all,

    I am confused. May I know the difference between the 2 battery source that I have attached. One is a 9V battery cell, the other one is a battery pack containing 6 AA batteries.

    Both supply 9V. What I think is that the current that they can supply is not same. Can anyone advise?

    Thanks and Regards,

    The small 9v battery has six tiny batteries in it.

    The battery pack can provide much more current than the tiny 9v battery.

    Or, the same amount of current for a much longer time.

    Simply look at the datasheets of the batteries on the website of a battery manufacturer like Energizer.
    At a current of 100mA, six AA alkaline cells last 5.5 times longer than a little 9V battery.
