What is the reason for the frequent loss of power in the car battery

Car batteries often lose power for the following reasons:

1. Even if the battery of the car is not connected to other electrical appliances, the battery itself will have a certain amount of power loss. If the car is not used for a long time, it will not be able to charge. When the car behind it starts, it will use a lot of power, so it will be easy to lose power. If the battery loses electricity once, the performance of the battery will drop a lot, the power of the battery will continue to decrease, and the service life will be shortened.

2. As long as the battery is still connected to the car, there will be electrical appliances that use the battery's electricity all the time. Even if the current is very small, it will add up to a lot, and electrical appliances that consume very little electricity will use a lot of electricity. It can be seen that if the car is not used for a long time, the pile head of the battery should be removed to save electricity.

3. The power of the battery has a cliff effect. The discharge curve of the new car battery is relatively curved and released linearly. However, the performance of the battery that has been used for a long time will decline. The power seems to be sufficient, but there is actually some virtual power. When the power reaches a certain level, it will suddenly run out of power.

4. There is also the influence of the weather. When the temperature is relatively low, the performance of the battery will be greatly reduced. In winter, there will be a situation where the battery runs out of power and cannot start a fire.

The service life of a car battery is affected by the usage of the vehicle, usually ranging from 1-8 years. The car generator is normal, there is no leakage of electrical appliances, and it can generally be used for more than 3 years.
