A method provided for detecting stratification within a vehicle battery. The method includes determining whether a state of charge of the vehicle battery is greater than a predetermined state of charge threshold. A determination is made whether a working capacity of the vehicle battery is greater than a working capacity threshold. A determination is made whether a voltage differential of the vehicle battery is greater than a predetermined voltage differential threshold. Stratification is detected within the vehicle battery in response to the state of charge, the working capacity, and the voltage differential being greater than the state of charge threshold, the working capacity threshold, the voltage differential threshold, respectively.
