Some use and maintenance methods of car battery

You don’t know about car batteries! The battery is the core component of the car’s electrical system. Assuming that the engine is the heart of the car, the battery is the key to activating the heart. Not only that, the battery will continue to be used during driving and continue to supply many electrical appliances, safety and comfort systems. Power such as car headlights, car audio, electric seats, etc. If there is a problem with the battery, these devices may not work properly. This is the primary reason for road rescue. We all know that different parts of the car have different resistance under different climatic conditions. In hot weather, the tires are the weakest; and when the temperature is low, the pressure on the battery is the greatest. So why is the battery so fragile at low temperatures? Knock on the blackboard! Knowledge! Generally, the best temperature of a battery is 25. Every time a drop of 1, the available capacity of the battery drops by about 0.8%. When the temperature rises, the capacity will recover. In low-temperature environments, many high-power devices such as seats, rearview mirrors, steering wheel heating, and glass defrosting require electricity, which adds a lot of electrical power. What is the warning before the battery fails? We all know that the normal car battery life is two and a half to three years. For general car maintenance, the master will replace it for you. Of course, the specific situation depends on your driving habits. The battery killer that loses power in less than two years is indispensable. When you encounter the following situations, I am sorry to tell you that your battery is not far from being replaced: 1. The car is more difficult to start than usual. There are no other factors, if you suddenly find that it is difficult to start the car, it may be that the battery is about to start. A sign of obsolescence. Of course, there is another situation in winter, the so-called cold start difficulty in winter. It depends on whether your car is new or the battery is almost dead. 2. When idling, the car headlights turn into candles. For example, when you stop at a red light or stop for a period of time, your car lights suddenly dim. This is because the charging power of the engine is reduced when it is idle. At this time, if the battery has no power and the electrical equipment of the car is powered, the headlights of the car will be greatly reduced. The battery failure warning light is on. There is nothing to say, the trouble light directly hints at you. You really have to go to a 4S shop or repair shop to check it. 4. The sound is abnormal when starting because the battery discharge becomes fragile, the engine does not work normally, squeak, this situation has special significance at low temperatures, because the weather is very cold, it will reduce the activity of the battery, and the weather will improve or disappear after In this case, many car owners do not care. 5. Observe oral changes. There is an observation hole and many free protection batteries. There is a light to show whether the battery is working well. The green is outstanding, and the black is to replace the battery, but there are also some car owners who reflect that the light is unreliable, and it is clearly green. Can not start the vehicle, for reference. 6. The battery is bulging and the water is still leaking. The important thing here is whether the battery is leaking or bulging. If this happens, it should be replaced in time. This situation is not only caused by the battery life, but even a certain amount. Safety hazards. 7. The voltage changes before and after the start. The normal battery voltage is about 12v. Later, due to the charging generator, the voltage is increased from 13 to 14v. Many car voltage detection functions. Note that the battery voltage before and after the judgment is also good, and it is less than 12v or launch vehicle after the start. Batteries smaller than 13v should be considered if there is a problem. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
