[Auto Repair Knowledge]The battery also needs maintenance

Many car owners thinkAccumulatorIt’s a very simple thing, and I don’t pay much attention to maintenance. In fact,carIn daily use, the battery is always an indispensable device in the car. Its working condition directly affects the performance of the electric system and electronic control device on the car, and even the phenomenon of the vehicle cannot be started or broken down. There are generally two types of batteries commonly used in our cars, the traditional lead-acid batteries and the maintenance-free batteries that have just been popularized in China in recent years. The maintenance-free batteries do not need to add any liquid. With less corrosion, strong resistance to overcharge, large starting current, long battery storage time, and long service life, it is more and more favored by consumers. At present, most cars use maintenance-free batteries. The service life of a car battery depends not only on the structure and quality of the battery, but also closely related to its operation and maintenance. Generally, the service life of a car battery is about 2 years, and if properly maintained, it can reach 3 to 4 years. At present, there are still many misunderstandings in the maintenance of batteries, which lead to the early damage of batteries, which should be paid attention to. Misunderstanding 1: When using maintenance-free batteries, simply think that maintenance-free means that there is no need for any maintenance. Misunderstanding 2: There is no corrosion on the surface of the battery pole post terminal, and it does not need to be treated, as long as it is not loosened.Corrosion appears on the outside, and corrosion appears on the inner surface of the terminal, resulting inresistanceIf the value increases, it will affect the normal charging and discharging of the battery, and it must be dealt with in time. Misunderstanding 3: When the liquid level is low, add electrolyte or add pure water instead of distilled water. If the electrolyte containing sulfuric acid is added, the electrolyte concentration inside the battery will increase, boiling, acid fog, etc. may occur, which will seriously affect the service life of the battery; use pure drinking water instead of distilled water, which contains a variety of trace elements , Has an adverse effect on the battery. Misunderstanding 4: The density of the electrolyte is not inspected and adjusted, especially when summer comes, resulting in insufficient battery capacity and even evaporation of the electrolyte. Misunderstanding 5: When using the battery to start in summer, use the starter uninterruptedly, resulting in damage to the battery due to over-discharge. In order to prolong the service life of the battery and avoid breakdowns such as breakdown, we should pay attention to the following points in the maintenance of the battery: 1. For maintenance-free batteries, always check the color of the electric eye. Green means sufficient power; black means insufficient power and need to be recharged; gray or light yellow means insufficient electrolyte. Because the maintenance-free battery cannot be filled, the battery should be replaced immediately. 2. The battery should be placed firmly in the car to prevent the battery cable from falling off due to vibration during driving, resulting in interruption of power supply. 3. Keep the surface of the battery clean. If solid oxides are found on the pole, they should be washed with hot water in time to remove them, so as not to affect the continuity between the pole and the terminal. After cleaning, wipe the surface of the battery clean, and put butter on the pole and terminal to ensure that the pole is not oxidized. 4. Check the height of the electrolyte at least once a month. For batteries without a marking line, the electrolyte can be added to a height of 10-15mm above the plate; for batteries with two red lines, the electrolyte must not exceed the upper red line, otherwise the electrolyte may overflow and form self-discharge between the positive and negative electrodes. Make the engine difficult to start, and shorten the battery life. 5. Adjust the concentration of electrolyte according to different regions and seasons. In the winter of our northeast, the concentration of electrolyte must reach 1.28 g/ml. 6. Cars that have not been used for a long time should be started every month or so, mediumRotating speedRun for about 20 minutes, otherwise it will take too long and the car will not start when it is used. 7. The total time to start the car each time is no more than 5 seconds, and the interval between restarts is no less than 15 seconds. In the case of multiple starts and still can not start the car, it should be from the circuit,Ignition coilsOr find the cause in other aspects such as oil circuit, and start the engine after troubleshooting, otherwise the battery will be over-discharged and its service life will be affected.
