Capacitor to charge a battery?

[Kennymadscience]

Hello all, ???
Does anyone have any links or insight as how to charge a regular 12 Volt deep cycle battery with energy stored in a capacitor?

I mean, I know a capacitor wont let current flow unless it is hooked up to something with less current across it, so I've heard. But, how many volts of the capacitor rating is too many for the battery to handle and then make the battery become explosive? I have multiple capacitors with energy in them, how can I recharge a 12 volt battery safely (one way diodes)? What should the ratings ofthe Capacitors be?
Anyone?

You guys are great, thanks. ;D
Ken

Hi Ken,

Well you have heard wrong, it

Regardless of other things, the energy stored in a capacitor is too less to charge the battery. You shall need capacitance in Kilo or Mega Farads to charge the battery ;D

Suraj,

This depends on the size of the battery and if he is filling his cap while charging. ;D

Ante, thanks. I see a 3 step charge controller being beneficial and applicable here.

Suraj, I do have homemade capacitors that hold VERY HIGH levels of energy, I will experiment designing one with less than the 30,000 - 50,000 volts it can hold now and one with more amperage capability.

Thanks for the insight,
Ken
