This was strange....my family took a 2 week vacation and my mom and I parked our Maximas in the garage. Well, when we got back, both of our car's batteries (hers a 99 se and mine a 97 se) were dead! This was the first time we both left our cars un-driven for a period of time. After recharging and driving, it's back to normal. Has this happened to anybody else? I wonder if it will happen again....
