Have a battery installation performed by a trained automotive professional at a shop such as Pep Boys service centers and Wal-Mart Tire & Lube, or install the battery yourself at home. To install a new battery, completely turn the vehicle off and disconnect the aged battery. Replace the old battery with the new one and reconnect the battery terminals securely.
When disconnecting the terminals from the car battery, remove the negative terminal first. The negative terminal is usually color-coded as black, whereas the positive terminal is usually red. It may be necessary to use tools, such as a wrench, screwdriver or pliers, to loosen the terminals before they disconnect. Terminals that are stuck to the battery may require a battery terminal puller to safely remove them without damaging the battery or the terminal cables.
Remove the clamp or strap that holds the battery in place using a wrench or socket and ratchet and remove the battery from its tray. Pep Boys recommends cleaning the battery tray using a water and baking soda solution to remove and prevent corrosion and rust that may have formed under the old battery. Use a wire brush to clean the terminal ends and, if desired, spray each with an anti-corrosion product. Place the new battery in the battery tray and tighten the strap. Attach and tighten the terminals, beginning with the positive terminal, and test the connection by starting the car.
