I have a 2001 mustang cobra and I have a similar problem. The battery always goes dead. I bought the car at an auction so I don't know much about it. The battery was even dead at the auction and it had to be towed home. We charged the battery and put a new clutch, cats etc. but if you don't drive it everyday it goes dead. I used to go to auto school and even tested the alternator and battery an both were good but I ended up buying a new battery and you had to drive the car every day if you go one day without charging it dies. Now even worse cant even go 24 hrs. Drove it one night and next day in the day was dead, well dead enough to not start the car. It always flashes theft. I have a keyless entry thing and it opens and closes the doors but doesnt activate the alarm. Any advice for me. Just got the battery warranty so has a new battery now that I put in today. Thank you.

The anti theft light should blink and that lets you know its active. The old battery probably had a bad cell in it making it weak. Come back to us if the new battery didn't solve your problem.
