You have something that's draining the battery. Something that is still using current even though you have turned the engine off. Something like a GPS or radio or fan or ??? Something that is still running or wired directly to the battery. One way to find out which circuit it is - With the key turned off, pull all your fuses - one at a time - and see if you get a spark when you re-insert it. The circuit that still has current flowing will spark a little when you push it back into it's place. Check all fuses. I am assuming this is an older car and this trick won't screw up a computerized car.

No, this will place a very heavy load on the alternator of the car and may result in burning out the diodes of the car charging the battery. You could easily ruin the alternator. Purchase a battery charger and charge the dead battery with that. Alternators are not made to charge dead batteries.
