Car battery maintenance

Many car owners think that the battery is a very simple thing, usually do not pay attention to maintenance, in fact, in the daily use of the car, the battery is also considered one of the most important parts, sloppy.

What should I pay attention to in the daily use of the battery? The reporter specially interviewed Zhou Yongjian, deputy general manager of Changqing Battery Co., Ltd. and Xu Jingxiong, general manager of Guangzhou Guangxiongsheng Industry and Trade Co., Ltd. Zhou Yongjian said that the battery has the distinction of starting battery and traction battery, and the starting battery includes maintenance-free battery and "water" battery. As far as the car is concerned, it is common to start the battery, because it can make the car store energy, and then release it instantly, so that with a good quality starter battery, the car starts more quickly.

Brand batteries are more secure.

Battery charging

Charging should occur when one of the following conditions occurs: the specific gravity of the electrolyte drops below 1.2; the discharge in winter exceeds 25%; the discharge in summer exceeds 50%; the light is dim; the start is weak.

Some car owners believe that fast charging can save time and only takes 3-5 hours. In fact, fast charging only activates the surface of the battery quickly, but in fact the internal battery is not fully charged.

In addition to fast charging, there is also a kind of slow charging, charging time is 10-15 hours, those who are deeply deficient in the battery must be slowly charged, otherwise the charging time is not enough, the amount of charging is insufficient, it will directly affect the driving performance of the car. Although charging is a fairly simple operation, there are some caveats: 1. Wear a protective clothing when charging a lead-acid battery. 2. When charging, there should be no sparks near the battery, and smoking is prohibited. 3. When charging one or more batteries in parallel, the charger voltage should not exceed 16V.

Some questions you need to be aware of regarding the use and maintenance of your battery:

1. The battery will not be used for a long time, it will slowly discharge itself until it is scrapped. Therefore, the car should be started once every certain time to charge the battery. Another method is to pull out the two electrodes on the battery. It is necessary to remove the positive and negative electrode wires from the electrode column. First, unplug the negative wire or remove the connection between the negative electrode and the chassis of the car. Then remove the other end with the positive mark (+). The battery has a certain service life and will be replaced in a certain period of time. The same order should be followed when replacing, but when the electrode wires are connected, the order is reversed, first connected to the positive electrode and then to the negative electrode.

2. When the ammeter pointer indicates that the storage capacity is insufficient, it should be charged in time. The storage capacity of the battery can be reflected on the instrument panel. Sometimes the power is not enough on the road, and the engine can't start. As a temporary measure, you can ask other vehicles for help. Use the battery on the vehicle to start the vehicle, connect the negative and negative poles of the two batteries, and connect the positive pole to the positive pole. .

3. The density of the electrolyte should be adjusted according to the standards according to different regions and seasons.

4. Distilled water or special rehydration should be added when the electrolyte is deficient. Never use pure water instead. Because pure water contains a variety of trace elements, it will have an adverse effect on the battery.
