Extreme temperatures often wreak havoc on car batteries. This is because the battery can't hold a charge at higher or lower temperatures. Car batteries are also less efficient and may not be able to start your vehicle under extreme conditions, which can lead to more wear and tear as you try to get it out of the cold or heat. If you live in an area that has extreme seasons, then this post will help you prepare for what these extremes might do to your battery!
The hotter the temperature, the less charge a battery can hold. This is because cells in batteries have different levels of acidity and compounds that keep them neutralized. When it's cold, though, acids become more acidic and this makes them harder to hold onto positive ions. These ions are needed to discharge power from your battery so if they're not there, then you'll be left with a battery that doesn't have enough juice to start your car.
If it's extremely cold, your battery is more likely to freeze completely and crack open. This can happen when it's 60 degrees Fahrenheit or colder outside.
