Note :
To calculate capacitance, the capacitor must be charged at
the rated voltage of 2.5V for 30 minutes. Measure the time of
duration ∆T (sec.) it takes go from 2V to 1V when a constant
current discharge of i (A) = 0.01 × nominal capacitance is
carried out. It is then possible to calculate capacitance based
on the calculation provided below.
Capacitance (F) = I × ∆T
