I found the hard way that I need to put my truck battery on a trickle charger once or twice a week. My wife does only short trips, she also needs to put her car on a trickle charger once a week.

Even when the alternator is working properly, it takes time to fully charge a battery. The battery might still be perfectly good. Put it on a charger for a couple of days. I use one of those 2 amp "computer controlled" chargers.
