AAA says this simple step could save your car battery this winter

Your car battery can also be affected by cold weather. These frigid temperatures can reduce a battery's ability to hold a charge. And AAA says it sees battery-related calls jump significantly. So how do you prevent that? AAA says have your battery tested if it's more than three years old. Park in a garage or sheltered area. Turn off the lights. Seat warmers and accessories before you shut off your engine. And listen for a slow cranking sound. That's a key warning sign that your battery is failing.
