Finding my battery had me stumped for a second in my 2004 Cadillac Deville. You do not have to take it to a repair shop to find out where the location is. That was a positive note. But this is something that every Cadillac Deville owner should know just in case you ever need to access your battery for any reason.
So the answer to the question where is the battery in my 2004 Cadillac Deville, the battery is under the rear seat. The battery is held in by a battery clamp and is situated under the back seat so it can vent and be stable during vehicle movement. Let’s dig deeper so we know more about the location and the importance of this location on our Cadillac Deville so we can better understand.

When do I need to replace the battery in my 2004 Cadillac Deville?
It is suggested that you replace your battery as scheduled preventive maintenance every three years. Once a battery gets to the four to the five-year mark, it is no longer reliable due to the wear and tears over time. Most vehicle batteries are sealed batteries, which means you cannot add additional battery acid over time to lengthen the lifespan of your battery.
I would not say this is a buying point if a vehicle, which I did see in my
research that some people will buy a car because of its battery. That is pointless to me due to the price of a battery on average being $80-$150 compared to the amount of the vehicle being tens of thousands. Think about it like your cell phone, the lifespan of the battery dissipates the more you use it.
This is normal when it comes to batteries due to the battery acid losing its consistency. Also, for all those that live in cold climate areas, it is highly suggested that you have a battery blanket or a battery warmer. Batteries are already dangerous, but when they become frozen, they are highly dangerous.
In the case that you have a frozen battery, do not try to charge or jumpstart the battery. This can cause the battery to explode and severely injure you. You can tell the battery is frozen because the sides of the battery will be swollen and bulging out of the side battery walls. When you are testing the battery, do not use a multimeter. This will only tell you the surface charge of the battery, not what the battery is at when it is under a load.
When you are starting your vehicle, this is putting a load on the battery. This is the voltage you need to know. So in this situation, we are going to use a load tester, this tool will tell you what your battery voltage is at under load. For a twelve volt battery, our battery should be able to maintain a minimum of 9.6 volts for fifteen seconds.
If the battery does not hold this minimum voltage for the allotted time, then the battery is bad and needs to be replaced. In the case that the battery does hold the minimum charge for the allotted time, then the battery is good and is operational.

Why do I need to replace the battery in my 2004 Cadillac Deville?
You need to keep the battery operational and well maintained at all times because the battery is the magic maker. Your battery makes everything work like it is supposed to. Think about it like this, when you want to start your vehicle the engine pulls the energy from the battery to crank the engine for the 1st time.
When your vehicle’s computer needs to make sure it has the right fuel to air ratio for the combustion process. The computer pulls that voltage from the vehicle’s battery. So the battery is more than just the thing that makes the vehicle start; it is the root of all that happens in the car, so make sure it is operational and safe.

How do I replace the battery in my 2004 Cadillac Deville?
Go to the rear seat, and on both sides of the seat, there is a pressure clip. Firmly grasp the bottom of the seat and pull up on one side at a time. This will free your seat from its transport position after you have done this to both sides; you can move the seat out of your way.
Now you can see the battery, and you are going to use a thirteen-millimeter
wrench to take off the battery hold-down bracket. Then we are going to get an eight-millimeter wrench and loosen the negative terminal on your battery first. Remove the negative (black cable) terminal then do the same to the positive (red cable) terminal.
When reinstalling the battery, you will put the positive (red cable) side on first then the negative (black cable) side on last. When placing your seat back in make sure that the bracket at the rear of the seat goes into its notched bracket. The bracket is under the back of the seat and the clips at the bottom of the seat. The clips need to go back into the same position as well.
Where do I replace the battery in my 2004 Cadillac Deville?
For this repair you can replace your battery in your 2004 Cadillac Deville anywhere you want to. If you do not feel comfortable with the repair, then let an automotive repair shop replace the battery for you or where ever you purchased the new battery. Always remember that the negative (black cable) terminal comes off of the battery first then followed by the power (red cable) side.
If you do not take them off in this order you can cause the battery to send a shock through your charging system, and it can blow a fuse, so be careful. The battery is an essential part of your vehicle that many people forget about until the battery is dead. You need to check your battery with your scheduled vehicle maintenance schedules. By doing this you always know your vehicle is going to start for you and repair costs maintain a low amount.
Now you know what you need to look for in your 2004 Cadillac Deville to make sure that your vehicle’s battery is up and operational at all times for your cruising pleasures.
