How Long Is the Car Warranty Period?

The car warranty period is 2 years or 60,000 kilometers, which means there are two limitations—one based on time and the other on mileage. Once either of these conditions is met, it indicates that the vehicle's warranty has expired, and any subsequent normal maintenance or repairs will no longer be covered for free. During the warranty period, not all repair costs are waived; it depends on the free services specified by the manufacturer. The car warranty period refers to the timeframe during which the automaker promises to provide free repairs and maintenance for any faults caused by quality issues. In reality, the warranty does not allow owners to freely request repairs or replacements as they wish. The warranty contract typically specifies different coverage scopes, such as warranty periods for critical components, major parts, comprehensive warranties, and full warranties.

How Many Years Does a Car Battery Last?

Car batteries typically last between 2 to 4 years. Conventional car batteries use lead-acid technology with a cycle life of approximately 200 to 500 charges. Vehicles equipped with automatic start-stop systems utilize specialized batteries that offer higher cycle durability, ranging from 400 to 800 charges, resulting in a service life of 4 to 6 years. New energy vehicles employ lithium-ion batteries, which boast extended longevity of 5 to 8 years. To maximize battery lifespan, proper usage habits and maintenance are crucial. When storing vehicles for extended periods, owners should disconnect all onboard electronics from the battery to prevent discharge. Avoid operating in-car devices or external power sources when the engine is off. Always ensure headlights are turned off when parking overnight. It's recommended to inspect the battery every six months.
