An arctic front will blast through Connecticut starting Friday, and experts say it's important to check on your vehicles.
Experts say if there's a time to focus on your car, it should be now, especially car batteries.
A local mechanic told News 12 if your battery is more than 5 years old, the more sensitive it will be to this weather.
AAA says some warning signs to look for are slow engine cranking, dim headlights, battery warning lights and the age of your battery.
They say to be prepared to plan ahead when it comes to your car battery.
"I guess the most important thing is the battery. Most car batteries are designed to last four and five years. But each 10-degree increment as it gets colder, the strength of the battery gets reduced exponentially so that's cold cranking amps, so the older the battery the more sensitive to the cold weather," said David Lawlor, of Shufelt's Garage.
AAA suggests opening the hood of your car to clean out the areas surrounding the battery for corrosion.
Mechanics say there are also other things to worry about in temperatures like this, including tires.
