What are the reasons why battery failure is more likely to occur in winter?

        Winter is the season of high incidence when vehicles are not easy to start, especially in the cold morning, it is more prone to the phenomenon of "squatting". Why can't I start the vehicle when I want to go out in the morning? The most common reason is that the battery fails.

　　The reasons for battery failure are more likely to occur in winter:

　　 1. Cold start of the engine at low temperature requires more electric energy

　　 At low temperatures, the oil viscosity is high, and the running resistance when starting the vehicle is greater, so the spark plug requires higher ignition energy. This allows the battery to have higher power support during cold start at low temperatures.

　　2, the battery performance is seriously attenuated at low temperatures

　　 The performance degradation of the battery is mainly reflected in the decrease of the electric capacity and the decrease of the charging efficiency. At low temperatures, the performance of the battery decreases, and at the same time, there are higher requirements for the battery when starting the vehicle. This becomes "the horse is required to run without feeding the horse", then it is normal for the horse to strike.
