How often:
If you need a jump to start your car in the morning, it might be time for a battery change. 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 a few simple tools however some vehicles have batteries that 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 giving the job to 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 store:
New battery
Battery terminal cleaning brush
Proper tools to remove the battery terminals and hold-down

Step 1:
Buy a replacement battery for your car.
You must know the make and model of your car to make the correct purchase. Knowing the BCI number is helpful as well. 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.

Step 2:
Open the hood of your car, using the prop rod to hold it in place.
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.

Step 3:
Unscrew the battery hold down clamp.
Lift the battery and remove it from the car. Inspect the battery terminal clamps. Clean and replace them if necessary.

Step 4:
Clean the battery tray.
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.

Step 5:
It is important to clean all corrosion from your battery.
Corrosion can be cleaned off by using a stiff brush and a solution of baking soda and water. 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 also carry anti-corrosive battery spray. This should be used and will prevent future corrosion.

Step 6:
Place the new battery into the battery tray.
Make sure that the positive and negative terminals are on the correct sides and install the battery hold-down. Reattach and tighten the positive cable first, then the negative cable.

Step 7:
Start your car.
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.

Step 8:
Dispose of the old battery properly.
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 Stores or NAPA AutoCare Centers.

Important Tips

	Wear gloves whenever working with batteries and follow all safety precautions listed in your owner’s manual.
	Your battery and charging system or alternator should be inspected at least once a year at your local NAPA AutoCare Center.
	Neutralize any electrolyte spills or corrosion with a solution of baking soda and water.
	Always remove the negative terminal first.
	Protect your eyes with safety glasses when changing a car battery.
	Never touch a metal tool across the battery terminal or from the positive post to any other metal on the car. Heeding this advice will help prevent large sparks and damage.
	Extinguish all smoking materials and open flames. Be cautious about creating any electrical sparks around the battery.
