Yes, it sure will. The alternator's purpose is to replenish the battery.
The alternator may either drain a battery while sitting if the diodes in the rectifier leak current (like a check valve) or may just not maintain the system load while your engine is running. (not keep up to the demand/not charge at all)

It could be two things. As you know, the alternator charges the battery so it will not drain. If the alternator is not working properly to charge the battery, the battery will continuously drain. Have the alternator tested at your local Auto Parts store (NAPA or Advance Auto) If it is good, have the battery checked.
