What is the service life of a Passat battery?

[DelAna]

Whether it's a maintenance-free battery or a conventional battery, the normal service life is around 2-3 years. With careful maintenance, it can last 3 to 4 years, equivalent to a driving mileage of 60,000 to 90,000 kilometers. If the battery cannot be charged or the starter is weak, and the headlights are noticeably dimmer, the battery should be removed and charged for 12-24 hours with a charger. Below are precautions for using the battery: 1. When the car lights are dim and red, the horn sounds weak, and the starter operates sluggishly: Stop using the battery immediately and charge it right away. Try to increase charging opportunities during use and keep the battery fully charged. In winter, ensure the battery remains fully charged to prevent the electrolyte from freezing due to low density, which could damage the battery. 2. If the first start attempt fails, avoid repeatedly trying to start the engine: From the perspective of automotive working principles, continuous starting of the motor will definitely cause excessive battery discharge and damage. The interval between subsequent start attempts should be more than 5 seconds.
