How Long Can a Vehicle's Battery Last?

[LondonMarie]

Car batteries typically have a normal lifespan of around two years. Proper maintenance can extend this period, with optimal usage potentially lasting over four years. When starting the vehicle, each attempt should not exceed 3 to 5 seconds, and the interval between consecutive starts should be no less than 10 seconds. Frequent short-distance driving and frequent starts/stops can lead to prolonged undercharging of the battery, thereby shortening its service life. Driving at a steady speed on the highway for 20-30 minutes allows sufficient time for the battery to recharge. During daily driving, before setting off, check and ensure all lights and other electrical appliances (such as the radio and CD player) are turned off, as they may drain the battery. If the battery is completely discharged, jump-starting might help to start the car. If unsuccessful, a dedicated battery charger should be used for slow charging. If the car remains unused for an extended period, the battery should be fully charged beforehand. Additionally, start the car once a month and drive at moderate speed for about 20 minutes. Otherwise, prolonged inactivity may make it difficult to start the car.
