Theoretically, the temperature of the battery will increase the temperature of most chemical reactions and will make it easier to start a car in the cold. Therefore, many car owners will activate the headlights for several seconds before turning on the engine.

Experts in the area of current chemical sources do not recommend the battery to be warmed up in this way. They advise you to start the engine at once.
