Under normal circumstances, car batteries can be used for 3 to 5 years. If the time is longer, it is likely that the vehicle cannot be started in winter.

　　Factors affecting battery life

　　Now the car battery life is directly related to the driving conditions of the car. If we often drive long distances and drive more than 20 kilometers each time, if the battery is fed, the vehicle generator can have sufficient time to charge the battery, and the battery level of the vehicle is relatively speaking. Higher, there will be no power feeding, so the battery life is longer, and it can be used by us for a little longer;

　　But if we often drive short distances, the vehicle often travels several kilometers, the car engine temperature has not reached a stable state, the owner has already reached the destination. In this case, if the vehicle battery has a power feeding phenomenon, the engine will have a short working time. Insufficient battery charging time and insufficient battery power can easily cause power feeding, which has a greater effect on the vehicle battery.

　　Battery feed damage impact

　　If the car battery is damaged by power feeding, this damage is irrecoverable to the vehicle battery. Every time the power is fed, the car battery is damaged once. If it is repeated several times, the vehicle battery will have a very low storage capacity, which is easy to cause the battery. Insufficient power, causing the vehicle to fail to start.

　　This situation often occurs in winter. Due to the low temperature in winter, the battery power is easily fed in a lower temperature environment. The vehicle starts cold the next day, the engine temperature is lower, and the internal friction resistance of the engine is relatively large. The starter needs The vehicle can be started only with a large amount of starting energy, which also requires a large amount of battery storage. This situation can easily cause the engine to fail to start.

　　The car battery is a very important component, which has an important impact on the starting performance of the vehicle. Every car owner needs to pay special attention to check the battery level in time during each maintenance to prevent the vehicle from starting difficult accidents due to insufficient battery power; if the power supply occurs frequently Phenomenon, we must also attract special attention.
