What causes the BMW 5 Series to fail to start due to battery drain?
1 Answers
BMW 5 Series fails to start due to battery drain because of long-term battery operation leading to abnormal current, power consumption, weather factors, etc. Car battery warranty period: Generally, the warranty period for car batteries is one year or 20,000 kilometers. Since the battery is a consumable part, the warranty period is relatively short. Regulations on battery warranty: Car owners can refer to the vehicle's three-guarantee manual, which clearly stipulates the warranty period for the battery. During the warranty period, if the battery has issues such as broken plates, short circuits, leakage, bulging, etc., and is confirmed by professional technicians as a quality problem, it can be replaced for free at the designated purchase point, usually without any charges.
