First, we’re excited to hear you’re going to college! Your dad is partially right: car batteries don’t last as long in extreme weather. But battery life expectancy typically fares worse in warmer climates like Texas or Arizona than in cooler-leaning moderate-climate areas like Minnesota.
Temperature extremes are never good for car batteries. Extreme cold or extreme heat puts a lot of stress on the battery, leading it to charge and discharge slowly and reducing its longevity. Car batteries do get a reprieve in the warmer months in Minnesota, but there’s a risk of waking up to find a dead battery when it’s super cold and yucky out.
Whether you’re in New Jersey, Minnesota, New Mexico, or just about anywhere else, it’s important you have your car battery checked yearly to avoid getting stranded on the side of the road somewhere. Once a year, ask a mechanic to check your battery while getting an oil change. It can save you a lot of headaches, both figuratively and literally down the road!
