The disclosure relates to an apparatus for diagnosing a battery of a vehicle, that may perform reliable diagnosis with respect to a voltage deviation of a battery of a vehicle, a battery diagnostic method thereof, and a vehicle system including the same. The apparatus for diagnosing a battery of a vehicle may include a voltage sensor measuring voltage with respect to a plurality of battery cells in the battery, and a processor diagnosing a voltage deviation of battery on the basis of the cell voltage measured by the voltage sensor. When the cell voltage deviation satisfies a voltage deviation diagnosis start condition, the processor determines whether or not the cell voltage satisfies a normal voltage range, and in response to a determination result, the processor may diagnose occurrence of a voltage deviation in abnormal cell voltage or occurrence of a voltage deviation in a normal cell voltage.
