How long does a ford fusion battery last?

A battery in a Ford Fusion will typically have a lifespan somewhere between three and five years. This could vary in either direction. So you could get less out of it, or more, with proper care and maintenance of the battery. To keep your battery performing at its best, check the terminals regularly for rust, and Make sure they are properly tightened to the battery. The weather can also have an adverse effect on your battery. So if you are using your car in extreme weather, you might get less service life from it. A battery replacement usually runs between $120 and $150. You can purchase one at your local Autzone or at a Target.
