If you need to jump start your car in the morning, it might be time for a new battery. You can bring your car to a NAPA AutoCare Center for a new battery or you can change it yourself.
Changing a car battery is a relatively easy job that can be accomplished with only a few tools. However, some vehicles’ batteries are located in tough-to-service areas such as under the front fender, under the rear seat or in the trunk. If this is the case, consider having it changed at your local NAPA AutoCare Center.
Your battery supplies the electrical current necessary to start the engine. It also provides necessary power to the electrical components and accessories even when the vehicle's engine isn't running. The battery also acts as voltage stabilizer for the whole electrical system.
Things you’ll need from your garage or your local NAPA AUTO PARTS Store:
You must know the make and model of your car to make the correct purchase. It also helps to know your battery’s BCI number. Car batteries come in different sizes, construction types, CCA (cold cranking AMPS) and ampere hour ratings. You want the replacement battery to match the original battery as closely as possible.
Locate the car battery and identify the positive and negative terminals. Positive terminals are labeled with a “+” or color-coded red. Negative terminals are labeled with a “-” or color-coded black. Loosen the bolt that holds the negative terminal and remove the negative cable first. Next, remove the positive cable.
Lift the battery and remove it from the car. Inspect the battery terminal clamps. Clean and replace them if necessary.
Use plenty of fresh water or a mixture of baking soda and water. Wait for the terminal clamps and the battery tray to dry before installing the new battery.
Corrosion can be cleaned off using a stiff brush and a baking soda/water solution. After removing the corrosion, rinse off the battery with water. Clean the battery tray by wiping it out with moist paper towels and mild detergent. NAPA AUTO PARTS stores carry anti-corrosive battery spray. Use this to prevent future corrosion.
Make sure the positive and negative terminals are on the correct sides, and then install the battery hold-down. Reattach and tighten the positive cable first before reattaching the negative cable.
Verify that the installation is complete and the cables are securely attached to the battery posts. Release the prop rod and close the hood of your car securely.
Car batteries contain highly toxic material and cannot be thrown out with your garbage. You can dispose car batteries at your local NAPA AUTO PARTS store or NAPA AutoCare Center.
