Supercapacitors are sized in farads: batteries are sized in watt.hours. Can they be compared?
Farad is defined as Coulombs/Volts; and has equivalences as Amp.seconds/Volt and Watt.Seconds/Volt^2.
Watt.hours is Amp.hours*Volts. Amp.seconds is 3600*Ah. Watt.seconds is Ah*3600*volts.
A 3.2V 3300mAh Cell has a (nominal) capacity of 3.2V * 3.3Ah * 3600 = 38016 Watt.seconds.
Divide by 3.2V^2 = 3712.5 Farads???
If so, that's also 3.3Ah * 3600s /3.2V = 3712.5 Farads. Does that make any sense?
