Every car has one and yet few people actually know how it works or what it does. We are of course talking about your car battery, and we here at Mercedes-Benz of Denver want to be sure you know the basics. A car battery is there for no other purpose than to provide a spark to start the engine of your car. Without it, your car wouldn't be going anywhere anytime soon.

Most car batteries last roughly four years, but this number can be higher or lower depending on the frequency with which you use your vehicle.
