It could also be a short somewhere in the wiring that is keeping power on all the time. I believe that you can just take the alternator out and get it tested at Autozone or someplace like that. If the car is just sitting and losing batteries then it probably isn't the alternator.

yes, it could happen. Mine was so bad that the battery was the only thing firing the computer AT 9 VOLTS! ! ! I had to push start it 3 times in one day and the whole car was literally running off the batt. Its 2 bolts and a serpentine pully, take it off and run to the autozone for it to get checked

Just try hitting the "Search" for 3G and you should come up with all the info you need.

Diagnostics before throwing money at parts is always wise. If your battery goes from being fine to dead because of a few days of inactivity, look for parasitic draw. Typical sources are glovebox lights, hatch lights, visor/vanity lights staying lit at all times, etc.

Use your DMM in series with the battery terminal and cable to check for current draw. Be sure your meter probe's and knobs are in the appropriate positions to measure current draw (in amps). Also ensure all interior and hood lights are off during your test.
Good luck.

I doubt that it is just the alternator, because I have run on just the battery for hours before. That makes me believe that it is something small just drawing on the battery throughout the week. Like everyone said just take your alternator out and take it to Autozone to get checked. You may get lucky and that be the problem, that'll be a lot easier than searching for something that is drawing power!

Good luck, hopefully it will work out for you and just be the alternator!

Exactly, I recently had a similar situation. It was a corroded terminal that connected to the alt. I checked pos. and neg. wires, ground connections, replaced terminals, etc.. I replaced the connector that attaches to the fuselink cable and the battery is now getting fully charged.
