A method for diagnosing a battery may include applying a generally constant current to the battery for a period of time, measuring a response voltage of the battery to the applied current, determining battery impedance parameters based on at least one of the applied current, period of time, and response voltage, and determining a degradation condition of the battery based on the battery impedance parameters.
