How to check the car battery?

Why do we learn how to check the battery first after the charging is slow and the battery feels less and less used in winter. 1. First, develop a good habit of checking the battery regularly. First, check whether the positive and negative connection wires of the battery are loose. If there is any looseness, please tighten it in time, and also look at the battery cover. Is the small hole still ventilating normally? 2. When inspecting the battery, if you find some white powdery crystals on the positive and negative connecting wires, it is more serious. Be sure to ask professional personnel or go to the repair shop for inspection and cleaning. 3. If you see a bulging battery during the inspection, it is also a very serious situation, and you should contact the repair station for repair in time. Or in winter, when the fire is no longer due to the temperature, you should also find a professional rider or a repairer to see if it is time to replace the spark plug. After talking about the above situations, everyone should take a look at which methods can lead to these situations. Below we will list some wrong methods or operations to prevent if the fire fails. If you fail to fire for the first time in winter, you must be careful not to keep firing. When we start the car in normal times, it can start successfully in about 3 seconds. If you still can't start the car in about 5 seconds, you should stop the start immediately, wait for about 15-30 seconds and start again. Make sure you don't start the car continuously. It will not be good for the spark plug and the motor. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
