I could boost it, drive it and restart it in the morning again but then it wouldn't start again and need another boost. Now I need to boost it every time I need to use it.

Just recharged my battery and the car started, but this is an on going issue for the last three years or so where my battery is drained or have to buy a new one. This is my third battery and just had it charged at an auto place and the car started it. Can it be a sensor, i do not think is my alternator. What you guys think?
