Yep, like @guybo suggested, have your battery load tested.

Meanwhile, you may consider putting the battery on a charger for a long, slow charge.

Be aware, if a battery has been run down, the alternator will NOT usually bring it back up to speed. The alternator will only replace the electrons that are consumed under normal operation.
