ABSTRACT:
A method for monitoring a battery includes the steps of activating a power conservation mode of an electrical system of a motor vehicle, measuring a duration of activation of the power conservation mode of the electrical system, and measuring a quiescent voltage of a vehicle battery of the motor vehicle. A battery status is determined based on the duration of activation of the power conservation mode and based on the quiescent voltage of the vehicle battery. Information indicative of the battery status is provided such that the information is perceivable outside the motor vehicle. A flashing pattern of a light emitting diode may for example indicate the battery status. A motor vehicle having a battery monitoring configuration is also provided.
