Someone online was driving a relative's car, and the battery went completely dead. He couldn't close the windows or lock the car, so he had to stay with it. He called AAA, and the guy said the battery was beyond help, so he bought a new one. I had never thought about a dead battery preventing the windows to close or the doors to lock.
I carry one of those little ni-cad battery jumpers in my car.
A car battery typically will last between 3 and 5 years.
