Super capacitors run light bulb and drill

[Magneticitist]

freakin awesome

[ImUrtastyflava]

how long do you think theses capacitors last? life time I mean... Are they like batteries?

[0nvd0]

@ImUrtastyflava They have much longer life than batteries but are more expensive and the discharge curve is not flat.

how long will it take to charge the capacitor

[0nvd0]

@KONGNO2000 Depends upon the current delivering capability of the charger and the internal resistance of the super capacitor.

I don't get this ? what's the difference if they act like batteries? am I missing something? I am working on an old laptop and I found a supercapaitor that I have to replace 5.5v .33f . I just don't get it ? I

@sweetgyy Longer life and faster charging time.

[mathscirocks]

it's probably a good idea to use thicker wire to hook up the inverter

[BackyardAmusement]

@mathscirocks - Right, it was just one of those spur of the moment things, not permanent.

how many volts to charge that capasitor can i use 6volts to charge that capacitor ????

[BackyardAmusement]

@panyolito1929 - The caps are 2.5v each. If you put two of them in series, you can charge to 5 volts, but at half the capacity. If you charge 2 caps individually, you can charge each to 2.5, then put in series to make full capacity 5v. If you overcharge, caps die.

@BackyardAmusement There is no difference if they are charged in series or individually. Capacitance of a capacitor decides after how much charge it will hit the full voltage. Thus the charge stored is the same in any configuration. Q = CV.

[BackyardAmusement]

@0nvd0 - I disagree. Capacitors charged in series will store less energy at the same voltage than if charged individually. Check out Google for more info, it's the same formula as resistors in parallel. ;)

@BackyardAmusement When two capacitors (each 2.5 V) are in series and 5 V is applied across them, they are fully charged. In series, the voltage applied is double. Thus same energy.

cooool hai i am from india . iam also working on this project ,making a bigger

cap bank . do u have any circuit for voltage regulator for the cell of a super cap

bank. do u know any thing about hybrid super cap. my email id-vishnu_c_10@yahoo.com.

Hey! Nice! How long could the system hold the charge? And by the way, A Perfect Circle in the background is also cool.
