How to Remove the Battery From a Cadillac DeVille

It only takes a few minutes to remove the battery from a Cadillac DeVille. It is a good idea to test the battery before removing it to see if it actually needs replacing. The Cadillac owner should make sure to buy a new battery that is an appropriate replacement for the old one.

1. Turn off your Cadillac DeVille and let it sit until the engine cools. Pop the hood and feel the battery to see if it is still hot before you try to remove it. Look at how the battery sits in the car to see if there is a strap that you need to unfasten.


2. Use a wrench to remove the black terminal connection from the battery. This is also the negative terminal. Place the black terminal out of the way so it does not touch the other terminal once you remove it.


3. Remove the red or positive battery terminal. Move the terminal out of the way and then check to see if there is a bolt holding the battery in place. Make sure that the two terminals are not close to touching, since this could result in an electrical shock. Loosen the bolt and then remove the battery from the Cadillac. Place the old battery off to the side.


4. Put the new battery into the Cadillac and fasten the bolt to hold it in place. Connect the red terminal to the new battery and tighten it with the wrench. Repeat the process with the black terminal. Fasten the strap to the new battery, if applicable. Use a rag to clean away any dirt from around the terminal connections. 


5. Start your Deville to make sure the battery works properly. Check the terminal connections if the battery does not work. Close the hood once you are done. Dispose of the old battery by taking it to a recycling center or to another location in your town that handles battery disposal.
