I was always under the impression that a 12 - 15 mile drive would fully charge a battery.
Provided of course that your alternator is good, and your not loading the system with lights, blowers and heated screens
Edit ~ It's probably the battery, but there could be a drain on the system somewhere. Take it to your local motor factor when it's charged, he'll be able to do a dump test for you. They usually do it for free, hoping for the sale
