How to Change Your Car Battery

Changing the batter in your car is easy, and it is something that everyone should know how to do.

Buy the Correct Battery

The first thing that you need to do is buy a new battery.  You should be able to find the correct type of battery at your local automotive store simply by asking an employee and giving them the make and model of your car.

Removing Cables

Replacing your battery is a simple operation.  Turn off the engine of your vehicle and open the hood.  Remove the black (negative) cable from the battery by loosening the nut with a wrench.  You can buy wrenches that are specifically for a battery, but most adjustable wrenches will work.  Twist and remove the cable. 

Once you remove the black cable, you will want to repeat the process with the red (positive) cable.

Pulling the Battery Out

To remove the battery from the vehicle, you will need to use a combination wrench to remove the clamp that holds the battery in place.  Once you’ve done this, you will be able to pull the battery out of your vehicle.  Keep in mind that batteries are heavy, and you might need someone there to help you.  Some batteries have handles that make them easier to remove.

Cleaning the Wires

Clean the connector wires with a wire brush to remove corrosion.  Clean off the tray with a wire brush water and baking soda for the same reason.

Put the new battery into place and secure it with the clamp.  Attach the red cable first and tighten it.  Attach the black cable next.  Make sure that the connections are tight and then start your car.  You can recycle the old battery at most auto supply stores.
