check all the lighting on the car, IE: trunk light,glove box light, light under the hood, any small light make sure they shut off ,check to see if you have a phone charger left in the cig. lighter, radar detector ETC. any of those things can drain a battery over night quick.if you dont find anything wrong then you may have a short somewhere in the electric system... hope this helps you...

Replace your battery when its being tested there not testing it under a heavy enough load. A battery could have a dead cell in it and still show good on the charger. I've had that problem a few times.
my cigarette lighter doesn't work in the front or the back...how can i fix this? i need it to charge my cell and GPS...=/

theres an anti-theft system. take positive terminal off battery, have someone holding the key on like trying to start it, then put the terminal back on and that should start it right up (had same problem in my dodge ram) if not, check all you're connections
SOURCE: the alternator isn't charging the battery
try this add an extra braided ground strap
i assuming you have all ready tested the out put of new alternator?? NEW doesn't mean it works .
assuming you done filed and diide continuity
checked and the polarity of alt,bat and regulator are all the same you added extra ground strap from block to fire wall. battery checks out. still no charge.get a new battery with more cold cranking amps.
