The Mazda 6 is a mid-sized car introduced to Mazda's vehicle line-up in 2002. The vehicle comes with four, five or six-speed transmissions, either standard or automatic. Mazda 6 owners who have owned their vehicles for five years or more should strongly consider new batteries. Consistent cold temperatures can also create the need for battery replacement.

Shut down the engine on the Mazda 6 and pop open the bonnet.

Loosen the mounting bracket using an adjustable wrench or a set of pliers. Remove the mounting bracket.

Remove the battery terminals, starting with the positive and moving to the negative. This may require loosening them with a 1/2-inch wrench.

Clean any corrosion from the terminals with a toothbrush soaked in water and baking soda.

Take out the dead battery and place the new battery on the battery tray.

Tighten the battery terminals on the appropriate battery posts of the new battery. Place the mounting bracket in its original position and tighten it down. Close the bonnet.
