You could have a faulty battery. But if you verified the battery holds a load and is fully charged, then you need to check for a parasitic draw, such as one you may have when a relay stays engaged (fuel pump relay, PCM relay, compressor relay for the suspension relay. etc...) Something may be staying powered at all times, running the computer down.
