After the car engine stalled listening to music "very hurt car"

Not long ago, the maintenance department of a brand 4S shop in Daling received a car repaired from the store. It is alleged that the owner of this vehicle has been accustomed to listening to music in the car after the engine has stopped working. As a result, the vehicle will not be able to start as time passes. After inspection, maintenance personnel found that the battery of the car had been damaged due to serious loss of electricity.

Maintenance staff said that especially since the winter, such cases are not uncommon. "A lot of people stay in the car to avoid the cold after parking. After the engine is turned off, the battery continues to work, and it is very easy to cause the battery life to be damaged."

According to reports, headlights, readers, radios, and other functions of cars are all electric devices in the car. Many car owners even install subwoofers and other electric appliances in their cars. In the case of the engine stopped working with the battery, how to avoid the loss of battery power?

New car battery scraps in one year

"The storage battery is the most easily overlooked part of car maintenance, but it is also one of the most important parts of the car." According to Mr. Li, the 4S shop maintenance staff, a car owner found him a few days ago and said that the car had just bought one. In more than a year, it suddenly became awkward. After Master Li’s examination revealed that the original battery of the car had been damaged.

It stands to reason that the battery life is generally about 3 years. Why is the car's battery scrapped after less than a year? According to Master Li, the original owner of the car had a bad habit of using the car. The owner is a shop owner who often drives to the wholesale market to purchase goods. In the process of waiting for goods, the owner likes to stay in the car, turn on the radio to listen to music when the engine stops working. “If the battery power is low, working for a long time will cause the battery to lose power.”

Oil and electricity are two important conditions for the normal start-up and operation of vehicles. Most of the on-board equipment used in the process of car use also depends on the vehicle's power generation and storage equipment. Master Li said that in fact, many car owners will continue to listen to music after parking. This seems to many people have become accustomed to, but do not know this is very hurt.

According to reports, after parking, in the case of a good car battery, turn on the headlights, reading lights, radios, capacity 35Ah battery working hours in about 3 hours, while the capacity of 45Ah battery working hours can be slightly longer, in 3 to 4 Between hours. The higher the volume of a radio or CD, the greater the power. In addition, the battery life is generally 2 to 3 years, so the new and old batteries also affect the duration of continuous power supply. If the user privately installs some appliances, such as a subwoofer, it will cause the battery to be over-used. If the battery is old, it is best not to work more than 2 hours.

Weapons

Electrical equipment should stop working before flameout

Today, more and more electric devices are on the car. Therefore, when the vehicle owner uses these electric devices, he should try not to overload the battery. Taking electric windows and skylights as an example, the owner should complete its lifting and closing before the engine stalls, because if the engine stalls, it will stop generating electricity. At this time, lifting and lowering the window will increase the load on the battery and cause damage to the battery. damage. The same is true for the lights. If there is no special need to turn off the lights, turn off the headlights first, then turn off the lights. When starting the car at night, turn on the headlights before starting to reduce damage to the batteries.

How to determine when the battery is charged, it will not allow the battery to lose power? Industry insiders, can not rely on the brightness of the headlight or the sound of the sound to determine the battery's power, because if the brightness of the lights until the dark, the battery has entered the state of loss. In order to ensure that the battery is working properly and does not allow the vehicle to “kick”, the owner should start the engine to charge the battery once every half hour when the battery is used.

According to industry sources, in the maintenance of automobiles, the maintenance of batteries is very important, but it is often easily overlooked. If you develop poor use habits, it will shorten the battery life or cause damage. If the use is not reasonable, the battery may be scrapped in advance for three to four months. If the battery is allowed to work when the engine is stopped, it is necessary to prevent the battery from being depleted, because the loss of power can easily cause damage to the battery. There is now a technology that can repair a damaged battery and use a pulse charging technique to activate the battery electrolyte. However, if there is a serious loss of electricity, the battery will be scrapped in advance.

Battery maintenance precautions

1. Check whether the two poles of the battery are eroded every month;

2, if the battery liquid level is lower than the minimum level, can add distilled water;

3, if the battery liquid level is higher than the highest level, you can carefully extract the excess;

4, keep the battery surface clean and dry;

5, the oxide of the battery electrode, please rinse with warm water;

6. If there is corrosive liquid, it needs to be washed out with water to keep the battery pole connection clean and connected firmly;

7. If the vehicle is not used within 3 days or longer, cut off the negative pole of the battery.
