Take care of your car, pay attention to battery maintenance

There are two main types of batteries used in automobiles, one is a lead-acid battery with an electrolyte, and the other is a maintenance-free battery. The length of service life of a car battery depends not only on the structure and quality of the battery, but also on its operation and maintenance.

The service life of a typical car battery is about 2 years, and it can be 3 to 4 years if properly maintained. In the season for a storage battery maintenance is essential. The maintenance-free battery is completely sealed without adding distilled water and adjusting the concentration of the electrolyte. Generally, no electrolyte overflows onto the surface of the battery. Its maintenance is very simple, mainly to check whether there is leakage, clean the surface of the dirt, handle the oxides of the two poles, tighten the clamps of the two poles and observe the color of the battery eye. The color of the electric eye is green for sufficient power; black is insufficient for power and needs to be recharged; gray or light yellow is insufficient for electrolyte. Since the maintenance-free battery cannot be filled, the battery should be replaced immediately. The maintenance of lead-acid batteries is more troublesome. In addition to the maintenance items of the maintenance-free batteries mentioned above, the following two aspects should be noted: First, check the height and concentration of the electrolyte, and the height of the electrolyte should be the highest ( Between MAX) and minimum (MIN), too low will reduce the capacity of the battery, causing the plate to vulcanize. If it is too high, it will overflow to the surface of the battery to corrode the poles, wires and the body. The concentration of the electrolyte has a great influence on the working condition of the battery. The sulfuric acid concentration of the electrolyte in our northeast winter should be adjusted to 1.28 g/ml. Note that the concentration measurement and adjustment must be carried out when the battery is fully charged; It is necessary to clean and unblock the exhaust pipe, keep the exhaust pipe well ventilated, and discharge the exhaust gas generated during the charging process in time. Otherwise, the electrolyte will overflow from the liquid-filling hole, which may even cause the battery to explode.

At the same time, in the actual maintenance process, some things need to be paid attention to by the owner:

1. When starting the car, the starting time should not exceed 3 to 5 seconds, and the interval between restarts should be no less than 10 seconds.

2, the car often drives short-distance, open and stop, will cause the battery to be in a state of insufficient charging for a long time, shortening the service life. Driving at a steady speed for 20-30 minutes on the highway, you can charge the battery for a full time.

3. When driving daily, check and make sure all lights and other electrical appliances (such as radio, CD) are turned off before leaving the car. Because this may drain your battery.

4, if the battery is exhausted, you need to use the fire (Jump-Starting, also known as the line) to start, you should immediately try to drive at a constant speed (such as highway speed) for at least 20-30 minutes, to fully charge the battery.

5. In the case that the battery is completely discharged, it may not be possible to start the car for you by the fire. At this point, you need to use a dedicated battery charger for slow charging.

6. If the car is not used for a long time, the car should be fully charged. At the same time, the car is started every other month, and the medium speed runs for about 20 minutes. Otherwise, the placement time is too long and it will be difficult to start.

7. Understand the battery life. Used for more than 4 years, it is recommended to replace.
