AnswerCould be a bad battery. Something staying on maybe and draining it like a door light or glovebox light.
check alternator could be going bad as well get the car started & un do the negative battery terminal if the car dyes its the alternator if it stays running your good!.... maybe a dead cell in the battery
I had the same problem, and it was because the air compressor never shut off (there was a leak in the system somewhere). If you hear it running for more than a few minutes, you can disengage it by unplugging it under the hood. In my RWD, the compressor was near the cabin, on the passenger's side.

A stuck relay in the car can drain the battery. A dead cell in the battery itself will drain the battery overnight. If this is the case the battery must be replaced as there is no way to fix it. To find out disconnect the negative battery cable for around 8 hours. If the battery goes dead it has a dead cell. If not then something is draining the battery. Anyplace that sells batteries can test the battery for you.
