How Do Extreme Temperatures Affect Car Batteries?

You're probably aware that your car's battery is more likely to die during a hot summer or a cold winter, but it turns out that there are some reasons for that. If a car battery is heated up too much in the summer, some of its electrolytes could actually evaporate. This can irreversibly lower the battery's lifespan unless the electrolyte is recharged. In fact, a battery's life may be cut in half for each increment of 15 degrees over the optimal operating temperature of 77 degrees Fahrenheit.

As for why batteries die in the winter, that usually has more to do with the fact that they need to work harder in cold weather. It takes a lot more energy to get a cold car to start, and even a brand-new battery can be pushed beyond its limits on a very cold day. On top of that, winter driving often involves regularly using headlights, windshield wipers, and other features that aren't used as much during the rest of the year. A depleted battery will also be more likely to freeze once temperatures drop below 32 degrees Fahrenheit.

While there is no way for you to control the weather and prevent your car from being exposed to extreme temperatures, you can prevent your battery from dying by keeping it charged. You can speak to a mechanic or dealer at i.g. Burton & Co. Inc. for more information about charging your battery or replacing it once it gets too old to survive in a harsh climate.
