In a method and an apparatus for diagnosing abnormality in an eco-friendly vehicle battery, the method includes determining and storing a defective cell candidate based on a voltage change of each of cells forming a battery module during an ignition OFF mode period of the vehicle, increasing a counter value based on a comparison result of a defective cell candidate during a recent ignition OFF mode period and a defective cell candidate during an immediately previous ignition OFF mode period, and detecting a cell abnormality based on whether a current counter value is greater than or equal to a threshold counter value.
