Um, no offense, but if the problem is your alternator and you buy a new battery instead, in about a week (or less) you'll have a dead battery, a dead car, be right back where you started, _and_ be out the price of a battery that you didn't need in the first place.
Anyhow, practically anyplace will bench-test your battery for free. If they say that it holds a charge, then the problem is not your battery, but your charging system (i.e. either bad cable connections or a bad alternator).
If you take the time to yank the alternator at the same time that you pull the battery (an extra 10 minutes should do it), then you can have both tested at the same time. One component will probably be good, the other will probably be bad, you buy a new while you're in the store, and you'll have fixed the car in one trip. Good luck...
