Yes, batteries just go bad over time. My battery that died this summer was about four to five years old and could no longer hold enough charge to start the car easily. The thought of a bad alternator crossed my mind, but I got a new battery and the problem was totally fixed. Alternator was perfectly fine.

If yours is over three years old (look around for a date written somewhere) I'd replace it just as basic maintenance.
