What is the cause of battery loss in cold weather?

The main reason is: 1. Vehicles use headlights for a longer time in winter; 2. The temperature is generally low in winter, which leads to poor oil atomization. Therefore, the difficulty coefficient of vehicle starting is much larger than that in summer, which will lead to vehicle emissions; 3. The low temperature in winter leads to the increase of battery internal resistance; 4. In low temperature environment, the viscosity of engine oil will increase, which will lead to the increase of running current of starting motor. If you want to prolong the service life of vehicle battery, you need to do a good job of battery protection in winter. The measures that car owners can take are as follows: 1. Avoid parking for a long time: if the vehicle needs to be prevented for more than half a month, it is recommended that the owner charge the battery of the vehicle every two or three days, or take out the internal battery before parking, and then install it when using the vehicle next time; 2. After using the vehicle every time in winter, be sure to turn off the power supply of the internal electronic system to avoid the phenomenon of running electricity when parking.
