Our daily lives run more smoothly when our car batteries are in good shape, but just like anything else, a car battery can't last forever and ultimately needs to be replaced. It's not usually the best idea to wait until the car breaks down due to a dead battery, but that's precisely what most of us would do. A dead automobile battery spells danger on a frigid winter day.

Your car's battery is its beating heart. It transmits the power in a chemical form, which is then converted into electrical energy and used to control the vehicle's electrical components. If power items are turned on after the engine is turned off, car batteries might become old or fail.
