Capacitor to charge a battery?


Recommended Posts

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?

You guys are great, thanks. ;D
