The misunderstanding of the battery?

A misunderstanding about the battery?

　　 Before talking about the maintenance of the battery, let’s talk about everyone’s misunderstandings about the battery. This is the biggest misunderstanding that you can’t listen to music when the vehicle is turned off. In fact, the battery is not as fragile as expected. As far as the capacity of most batteries is concerned, there is no problem with parking for hours of music. There is also a misunderstanding that the batteries of the same car are the same. In fact, even the same car model has some differences due to different batteries, such as automatic start-stop function.

How to extend the battery life cycle?

In fact, those mentioned above are not very useful to most car owners, because the battery is changed directly to the repair shop or 4S shop. The biggest significance for car owners is how to maintain the battery to extend the life cycle of the battery. The way to extend the battery life cycle is nothing more than preventing the battery from over-discharge and damage.

　　 Turn off the engine and use the electrical equipment in the car for a long time, it is very easy to cause excessive discharge, such as audio, lighting, air-conditioning, for the new battery, these electrical equipment use dozens of other than car lights Minutes are not a problem, but if the battery is aging, try to avoid it. In addition, the inverter of the power supply in the car and the high-power electrical equipment provided by the inverter, such as small vacuum cleaners, air pumps, etc., must be used after the car.

　　When the engine starts, the battery will discharge with high current, but long-term high current discharge will greatly damage the battery. Therefore, each start time should not exceed 5 seconds to avoid long-time high-current discharge and battery loss. If the start is unsuccessful, the next start must be more than 10 seconds apart. This will allow the battery to have some buffering and prevent battery damage.

　　 Another thing that needs to be done is to regularly check whether the battery positive and negative connections are loose. If there is any looseness, they should be tightened in time. At the same time, regularly check whether the small holes on the battery cover are ventilated. If the small holes in the battery cover are blocked, the generated hydrogen and oxygen cannot be discharged. When the electrolyte expands, the battery shell will be broken and the battery life will be affected.

　　 The last point is about the problem of long-term parking. Many old drivers will tell you that the vehicle must be turned on regularly when parking for a long time, or the positive and negative electrodes of the battery should be removed. This time the old driver was really right. The reason is that in the manufacturing process of the battery, there will always be impurities, so the battery will inevitably have the phenomenon of automatic discharge. If the vehicle is not started for a long time, the battery is very likely to be over-discharged, causing damage to the battery. Therefore, if the vehicle is to be parked for a long period of time, it must be driven once a week or the positive and negative poles of the battery must be removed to power off.

　　 If you want to know if the battery is still in use, you must first know if the battery has electricity. For maintenance-free batteries, it is very simple to check the battery level. Generally, there is a battery indicator hole on the top of the battery. If the display is green, it is normal. If the display is light yellow or colorless, it means that the battery is insufficient and needs to be replaced in time. If the battery does not have a battery indicator hole, you can go to a repair shop or 4S shop to check it with a professional battery tester.
