The longer the battery is in your vehicle, the more it has to deal with the extreme cold and heat every year. These huge swings in temperature are having a negative impact on the car battery in a number of ways.
When the temperatures outside begin to plummet, the car battery has to work harder to be able to perform the chemical reactions needed to get power. If the temperatures get too extreme, the liquids inside of the battery may become thicker, expanding and pushing the boundaries of the casing, causing even more damage.
