    The battery drains because of any accessory load left open or grounded. However, you can't keep constantly buying new battery when the old one drained of charge, it will just drain some money out of your pocket. Perhaps, it was drained because some accessories are using the battery power to function but the charge was not replenish back by the faulty alternator. Click the links below that shows how to trouble shoot or diagnose the battery and alternator.
