What is the national standard warranty period for car batteries?
2 Answers
National regulations stipulate that the warranty period for automotive batteries is one year or 20,000 kilometers. The production date of car batteries is usually printed on the battery surface, represented by a series of numbers and letters. Since batteries are considered consumable parts under the three-guarantee policy, warranty periods vary by brand, mostly covering 1 year or 20,000 kilometers as specified in the battery manual. Below are car battery maintenance tips: 1. Avoid prolonged vehicle parking: Installed car batteries self-discharge when left idle for extended periods, so it's recommended to drive the vehicle at least once a week for over 20 minutes to allow the battery to recharge during operation. 2. Close windows before turning off the engine: Power windows and sunroofs operate on battery power, so all windows should be closed before engine shutdown rather than after, avoiding using the long-press lock button method for window closure after leaving the vehicle. 3. Maintain battery cleanliness: Regular inspections effectively extend battery life. Use professional battery terminal brushes or old toothbrushes to clean positive/negative terminal dust and corrosion. Applying vaseline or grease forms a protective coating on contact surfaces.
As a car owner who has used several vehicles, I can tell you there's no unified national standard for automotive battery warranty periods - it's entirely up to the manufacturers. Typically, new batteries come with 12 to 24 months of warranty. The last battery I replaced had an 18-month warranty. When purchasing a car, carefully review the purchase contract or manual as these documents specify the details. While China's Three Guarantees Policy covers key vehicle components, batteries are considered wear-and-tear parts and usually have shorter warranty coverage. From my experience, regularly cleaning the terminals and avoiding deep discharge can extend battery life, but I still recommend periodic inspections to prevent sudden breakdowns. Poor maintenance may void the warranty. Ultimately, understanding these points can save you money and hassle - safety always comes first.
