What is the warranty period for car batteries?
2 Answers
Car batteries generally have a one-year warranty period. The warranty duration is calculated from the date of vehicle purchase. Additional information: Below are precautions for battery maintenance: 1. Avoid long-term outdoor parking: Refrain from leaving the car parked in open-air parking lots for extended periods. If long-term parking is necessary, the battery must be removed and taken away to prevent freezing damage. 2. Engine starting: Car engines are harder to start in winter. Each starting attempt should not exceed 5 seconds, with intervals of no less than 15 seconds between attempts. If the engine fails to start after multiple attempts, check other aspects such as the electrical circuit, ignition coil, or fuel system. Avoid continuous starting attempts, as this may cause the battery to over-discharge and burn out. 3. Charging issues: Unused batteries will gradually self-discharge until they become unusable. Therefore, start the car periodically to recharge the battery. 4. Regularly inspect battery components and connections: Clean the battery terminals periodically and apply specialized grease to protect the wiring harness.
Last year, I bought a new car, and when I went for repairs due to battery issues, I learned that the warranty period is typically one to two years, but it varies significantly between brands. For example, regular lead-acid batteries usually come with a 12 to 24-month warranty, while premium brands like Mercedes or BMW might offer up to three years. The salesperson told me that factors influencing this include the battery type and usage environment. If you live in a cold northern region, the battery ages faster, and the warranty period might be shorter. I recommend carefully reviewing the warranty manual when buying a car and keeping the invoice and warranty documents. If the battery fails within the warranty period, don’t delay—visit the 4S shop promptly for a free replacement. Remember to regularly check the battery’s health, avoid over-discharging to extend its lifespan, and generally test the voltage and clean the terminals every six months.
