Cold weather can affect your vehicle and auto batteries are one of the engine components that see the highest risk.
Batteries are filled with fluid containing mostly water and can be susceptible to freezing when the battery is not fully charged. Cold weather also thickens engine oil, forcing the battery to work harder when starting the car. Car batteries can lose 35 percent of their efficiency when the temperature dips below freezing. That percentage can spike to nearly 60 percent when the temperature falls below zero.
"Motorists should have their battery checked when they learn of an incoming wave of cold weather," said Interstate Batteries engineering services manager Gale Kimbrough.
Kimbrough said, "A fully charged battery is the best defense against cold weather and vehicle non-starts. In cold weather, engines require more cranking amps and batteries are less efficient, reducing their charge acceptance and ability to start an engine."
Interstate Batteries recommends taking special precautions with your vehicle battery this winter:
If your car has a lot of bells and whistles – such as electronic fuel injection systems, electric windows, sun roofs and audio systems – the battery should have more power to account of all the features. The best guarantee against failure when cold weather strikes is a battery with a high charge level and adequate cold cranking amps, 500-700, depending on the type of engine in your vehicle.
