Recently, a Miss Cai purchased a luxury brand model and did not expect the battery to become unusable after using the car for a year and a half. So Miss Cai went to the 4S store and after inspection, the other party informed her that it was because the natural lifespan of the battery had ended, and the battery was not covered by the warranty. But she saw in the warranty manual that the warranty period is 3 years or 100000 kilometers, and she bought her own vehicle for less than 3 years and drove less than 100000 kilometers. The dealer asked her to consult with the manufacturer. After consulting with the manufacturer, the other party also stated that the battery is not covered by the warranty, and there is no information about battery warranty in the warranty manual. After several negotiations, the manufacturer suddenly changed the statement that the battery did not end its natural lifespan, it was an abnormal malfunction, and she still does not know how to solve it.

Answering questions and clarifying doubts, batteries enjoy warranty with conditions

According to the newly introduced Automobile Three Guarantees Law, a warranty period of three years or 60000 kilometers (whichever comes first) is the warranty period for automobile three guarantees. As the name suggests, if a vehicle experiences product quality problems during this period, consumers can have the repairman repair it free of charge (including labor and material costs) with a three guarantee certificate. However, it should be noted that the vulnerable and consumable parts of the vehicle have a separate warranty period. There are a total of sixteen types listed as vulnerable parts along with batteries, each with a different warranty period. The warranty period for the battery is one year. If Ms. Cai's vehicle battery encounters problems within one year, she can enjoy free replacement.

Industry maintenance experts have pointed out that quality issues with batteries include: short circuit, partition penetration, reverse installation (reverse placement of the electrode group during assembly), improper liquid injection (such as high or low initial liquid injection density), leakage (poor battery sealing), and powder removal (poor bonding between the grid and active substances). It is not a quality issue, but mainly due to improper use, such as excessive discharge, prolonged use, insufficient charging, overcharging, high current during charging, insufficient charging, reverse charging, powder shedding (high charging current), liquid leakage (caused by collision), short circuit (self modification), etc. Improper human maintenance mainly refers to the practice of frequently parking and turning on the audio system, frequently driving and turning off the engine in the city for a long time, and rarely running on the highway.

But now many 4S stores do not inform consumers to learn about vulnerable parts from the repair manual when selling vehicles, which ultimately leads to disputes over future repairs. Meanwhile, the types and warranty periods of vulnerable parts are not uniform among manufacturers.

The reporter noticed that among major luxury brands, some brand repair manuals clearly stipulate that the battery bottle can be replaced for free within a one-year warranty period, and between 12 and 24 months, the owner needs to pay 25% of the cost. Some brand batteries can be replaced for free if they are damaged after two years of use and within 100000 kilometers of driving; If two years later, less than four years later, and the mileage is within 100000 kilometers, the owner needs to bear 50% of the cost.
