What are the precautions for replacing a car battery?

[VanZoe]

Car should be stopped and turned off, confirm the battery model, as the capacity and size of the battery vary, it is best to choose the same battery as the original one. Here are some relevant introductions about the battery: 1. Since the battery is heavy, friends with low strength are advised to seek help from others, especially when taking out and placing the battery from the engine compartment, to avoid damaging the battery or hurting themselves. Remove the battery clamp and take out the battery. If the vehicle is connected to an external power source, be careful not to let the positive terminal wire come into contact with the car body. It can be isolated with cotton cloth. 2. Generally, the service life of a car battery is 2-3 years, and the original battery of a new car can last more than 3 years. If the battery has been used for almost two years, pay attention to its service life which may have expired. At this time, you should check more often, conduct inspections in advance, and solve or replace any problems as early as possible to avoid losses caused by the battery suddenly "dying" during use.
