You'll need to get the battery coded to the vehicle - basically the alternator pumps more and more into the battery as its ability to store charge decreases. If you put a fresh battery without telling the car, the alternator will overcharge the new battery and severely reduce its ability to hold charge. Some accounts claim that within 6 mths the new one will be stuffed too.
