The Mazda 6, a sporty mid-size car, is available as a sedan, four-door hatchback or station wagon. Changing out the battery is a relative easy job. It is conveniently located on the driver's side, near the engine wall. Most batteries should last about 5 years, but if you see a white, chalky substance on the battery, replace it with a new one.
