The Peukert formula for battery capacity at a given discharge current is: Cp = battery capacity available with the given discharge current I = the discharge current level n = the Peukert exponent = log T2 - logT1 : log I1 - log I2 T = discharge time in hours. I1, I2 and T1, T2 can be found by carrying out two discharge tests.
