The battery in your vehicle can be subjected to overcharging if it is sweltering outside. The overcharging eventually kills your battery, and you'll have to have it replaced. There is also corrosion when the temperatures get hi which will start to deteriorate a battery. Finally, evaporation can damage the inside of a battery because it causes the battery fluid to decrease.
In frigid weather, car batteries have a lot harder time starting your vehicle, and they have to work harder because you will usually run more things the colder the weather gets outside. Running a battery at reduced capacity and forcing it to work harder in the cold will eventually cause it to die.
