Summary of relevant experience in car battery charging

The car battery is definitely very important to our driving. There are many car owners in Chongqing who have not understood how to charge the car battery until now. If the car battery is out of power, it will directly affect our normal use. The editor will summarize some today. The relevant experience of car battery charging is a reference for everyone. Regularly recharge the battery of the car in use: 1. First adjust the liquid level of the battery to the specified height with distilled water or special replenisher for the battery. 2. Connect the battery to be charged according to the rated voltage and rated current of the charging equipment before charging. The total voltage of the batteries connected in series cannot be greater than the rated voltage of the charging equipment. 3. The charging current for constant current charging is selected according to the capacity of the battery. The constant current charging is carried out in two stages. The charging current of stage one is one-tenth of the rated capacity of the battery, and the charging current of stage two is one-twentieth of the rated capacity of the battery. 4. After the battery is fully charged, check the density of the battery's electrolyte. If the electrolyte density does not meet the requirements, you can pour out some of the electrolyte in the original grid; if the original density is too small, you can add a relatively dense electrolyte; if the original density is too high, you can add distilled water to dilute. The height of the liquid level after adjustment should meet the requirements. How to use the car battery: 1. Develop a good habit of using electricity in the car. The most important thing in car battery maintenance is to develop good electricity usage habits. For example, you can’t listen to the radio loudly, charge your mobile phone, use charge pumps, etc. when the flame is turned off. This will cause the battery to lose power over time, and the battery loses power. The more the frequency, the life expectancy will be greatly reduced. 2. Regular high-speed and long-distance running. Regular high-speed running has many advantages. It can not only remove carbon deposits from the car, but also make the battery overflow with electricity. Generally, running at high speed for more than an hour will basically overflow the car battery, and such a battery can maintain its best condition. 3. Don't leave the car on hold for a long time. If the car is not used for a long time, such as 20 days or a month, the battery cable should be cut off, or the car should be driven for tens of kilometers after two weeks to ensure that the battery can be used normally. 4. Be careful not to use high-power electrical appliances to connect the battery directly. At present, many on-board electrical appliances, such as on-vehicle refrigerators, vacuum cleaners, air pumps, etc., have a very large instantaneous power. Do not use the car battery to supply power directly. The vehicle should be ignited first, and then the electrical equipment should be connected. This is a good protection for the battery. Maintenance of car battery: 1. Do not start the car frequently. Many car owners will encounter the problem that the car is difficult to start in winter, so it is difficult to start, so they will start frequently. But the correct approach should be: do not exceed 3 seconds each time you start the engine. If the first start fails, don't rush to start repeatedly. From the working principle of the car, starting the motor continuously at this time will definitely cause the battery to be over-discharged and damaged. The time between re-launching should exceed 5 seconds. 2. Foresee the precursor of a battery strike. Some batteries will have a large internal resistance when they are worn out, and there will be a phenomenon that the battery will be fully charged and discharged. The car owner should test the battery for routine maintenance when the battery life cycle is about two and a half years, which can play a preventive role. Forgetting to turn off the lights in the car when parking and turning off the car, this is a small mistake that many new car owners make. After the battery is consumed overnight, it may be out of power at any time and the car cannot be started. In this case, if conditions permit, you can try to charge the battery. If it still doesn't work, the battery may need to be replaced. Try not to use electrical equipment such as CDs and cigarette lighters when the vehicle is not started, and use less on-board electrical appliances during driving. 3. Turn off the air conditioner before turning off the flame. Most car owners are used to not turning off the air conditioner or letting the air conditioner start automatically after the vehicle starts. This will cause the air conditioning system to automatically start working every time the vehicle’s ignition switch is turned on. The consequence is that the vehicle will directly cause instant power If the load is too high, the battery will be wasted for a long time.
