Avoiding the dreaded "short trips"

How far does a car need to be driven to charge the battery?

Mrs. VTX and I bought our first house (yay!) six months ago and one of the benefits is that it is MUCH closer to where she works. Recently, the battery in her car (a 2006 Mazda 3s) died after the car had sat around for four days. The battery was original so it probably needed to be replaced anyways but I'm worried that my wife's short commute will start burning up batteries.
She drives 3.8 miles to work, the car sits in a covered but otherwise open parking ramp for 8 hours then she drives 3.8 miles home all on side streets, never faster than 40 mph. Other than that, we take my car everywhere else so it almost never gets driven anywhere other than to and from work. We're in Minnesota in case the cold of winter is relevant.
Is this a long enough drive that the battery will get charged regularly?
Are there any other issues that this sort of use will cause?
Are these trips long enough to avoid being "short trips"?
