I have a trimmer which uses 1.2V 600 mah AA battery. Is it possible to replace it with a super capacitor ? Reason to replace is that the trimmer takes about 5-6 hrs to fully charge itself but the super capacitor (SC) can be charged in few seconds.
I googled a lot ( and still trying to find ) if this was feasible and what specification SC I would need. From what I found I google I would need a SC with a voltage higher than charging voltage of trimmer so I guess 2.7v SC will be enough but how do I find how much Farad capacity capacitor I would need ? Can I connect the SC directly to the positive and negative terminals where I insert the Ni-Cd battery ? Will I need any stabilizer or anything of such short to stabilise the output of capacitor. How long will the charge last ? Can it last enough so that the trimmer can do its job i.e. trim the beard ?
