Note :
The capacitance calculated from discharge time (∆T) with constant current
( i ) after 30minuite charge with rated voltage (2.5V).
The discharge current ( i ) is 0.01 × F (rated capacitance).
A discharge time (∆T) measured between 2V and 1V with constant current.
The capacitance calculated bellow.
Capacitance (F) = i × ∆T
