Someone asked me this question recently and I had a minor existential crisis.

Anything at all is vastly better than sitting around all day.

A week is not a very long time to leave a car alone, and 3 batteries in 5 years is a lot.

Did you have the batteries tested, or did you just replace them when they stopped being able to start the car? Could it be a problem with the alternator?
