Car battery maintenance and care
Many car owners think that the battery is a very simple thing, and usually pays less attention to maintenance. In fact, in the daily use of the car, the car battery is the main energy storage device in the car, providing power to all the electronic systems on the vehicle, its importance is undoubtedly one of the most important parts, sloppy. The maintenance and maintenance of car batteries is very important.
1. Prevent metal from rusting. For vehicles that have been parked for a long time, keep the metal surface clean. Always keep ventilation in the garage of the parked vehicle to keep the relative humidity of the air below 70. It is necessary to remove dust, dirt and moisture from the car in time. The surface of the rust and the surface of the machine should be coated with oil, grease or wrapped with oil paper. The pores in each assembly should be sealed to prevent air, moisture and dust from entering the interior.
2. Prevent aging and deterioration of rubber products. Rubber products on automobiles, such as tires, transmission belts, and dust covers, often age, swell, or shape, resulting in poor performance and a shortened service life. In order to prevent the aging of rubber products, direct sunlight and mineral oil contact should be avoided.
3. Prevent the mildew of cotton and linen products. Cushions and rugs are easy to absorb moisture. Especially in wet areas and rainy seasons, it is more susceptible to mildew. Therefore, the owner should check the cotton and linen products on the car frequently, and dry it at a proper time to keep it dry.
4. Prevent the antiknock performance of gasoline from decreasing. The antiknock performance of gasoline is determined by the level of gasoline octane. When the car is stopped for a long time, the octane number of the gasoline will decrease with the loss of light components and the content of the gum, which will reduce the explosion resistance. Therefore, the gasoline tank should be tightly sealed and the temperature should be kept too high. It is best not to store the gasoline for too long.
5. Always check the working condition of the engine. Start the engine at least once a month and idle for 4-5 minutes to check the engine operation. If there is an abnormal phenomenon, it needs to be adjusted and repaired in time. Also, check the battery frequently. The electrolyte liquid level of the battery must be 10-15mm higher than the electrode plate. When it is insufficient, the distilled water should be added in time. The battery should be kept fully charged and the battery should be charged if necessary.
