What are the regulations for the three-guarantee period of automotive batteries?

Here is a detailed introduction to the three-guarantee service: 1. Repair Guarantee: Within 60 days from the date the seller issues the purchase invoice or within 3,000 kilometers of driving distance, if the home-use automobile product experiences steering system failure, braking system failure, body cracking, or fuel leakage, the seller is responsible for repairs. 2. Replacement Guarantee: During the three-guarantee validity period of the home-use automobile product, if it meets the replacement conditions, the seller should promptly replace it with a new qualified home-use automobile product of the same brand and model for the consumer; for replacement with a different brand but the same model, the seller should replace it with a home-use automobile product that is not inferior to the original vehicle configuration. 3. Return Guarantee: During the three-guarantee validity period of the home-use automobile product, if it meets the replacement conditions but the seller does not have a home-use automobile product of the same brand and model or one that is not inferior to the original vehicle configuration to replace for the consumer, the consumer can choose to return the product, and the seller is responsible for the return. Additional Information: The warranty period for automotive batteries is one year or 20,000 kilometers. The warranty period refers to the time from the product's factory shipment until quality issues arise. It is possible that some products may still maintain normal conditions after this period, hence there is uncertainty.

Last year when I had battery issues with my car, I specifically asked the 4S dealership. According to national regulations, the battery as a major component is covered by the three-guarantee policy for at least 2 years or 50,000 kilometers, whichever comes first. At that time, my car was only 1.5 years old but had already traveled 52,000 kilometers, so I qualified for a free replacement. The specifics may vary depending on the purchase contract or warranty manual - some brands may extend coverage to 3 years, like a certain German brand that offers a 3-year battery warranty. I’d like to remind everyone to keep maintenance records properly, as modifying circuits may affect warranty rights. Obvious human-caused damages like battery case deformation or electrolyte leakage are not covered by the three-guarantee policy.
