Well, it is likely one of 2 problems. 1.) The alternator is not charging. Use a volt meter to check. The voltage should rise to 13 - 14 volts with the engine running above idle. 2.) There is something draining the battery (interior light, under hood light, radio or accessory staying on). Need to do a check for anything drawing current with the key turned off.
