Thank you all for your help and info. Much appreciated. I'm not very techie when it comes to theses types of things, would love to be though. Ended up buying a charger/booster as i was worried that i would blow something other than the battery. Thanks again and sorry for the late reply.

It would be really hard, because the voltage needs to be up-stepped;

I suppose you are thinking about using the +12 and -ground lines of the psu for charging your car battery?  Well a 12V car battery does emit +- 12 volt, but to fully charge it, it needs to get more around 13,2-13,4 volts of juice. this is because of the internal resistance of the battery and also a fully charged car battery will emit a bit more then 12 volts. so direct charging without up-stepping wont really charge your battery that much(it would charge it to like 20% of the capacity if your lucky)
