The present invention is to provide a system and a method for determining a battery replacement time. The system for determining a battery replacement time comprises: an SOC calculation unit which calculates, when a first battery and a second battery provided in a vehicle enter into a sleep mode or a wake-up mode, an SOC (state of charge) difference value between the first battery and the second battery; and a replacement time determining unit which compares, when the calculated difference value is larger than a threshold value, the SOC change values of the first battery and the second battery during the sleep mode, and reports a replacement time of the battery having the larger value of the SOC change values. |
