Hi, I'm not sure about how manufacturers calculate the maximum constant current that a battery can discharge. I understand that a battery capacity rating is given by 20hrs multiplied by the maximum current value.
I learned also that by shorting a 9V battery of internal resistance 0.01ohms, we will not get 900A of current running through a circuit, hence ohm's law does not apply.
I'm quite sure this should be related to the energy stored within the battery, but due to the limits of my knowledge the only formula I know is energy= V x I x T. I can't put a value for time in this formula though!
