Get the Right Tools and Materials
When you are going to disconnect a car battery, you must first get the right tools and materials for the job. This will ensure that you can disconnect your battery properly without causing permanent damage and without injuring yourself.
Some tools you may need are socket wrench sets or an adjustable wrench, wire cleaning brushes, and heavy-duty shop towels. If your battery is corroded, you may also need to buy some anti-corrosion grease or anti-rust spray.
Take Safety Measures
Next, you need to take the proper safety precautions to protect yourself before you attempt to remove your battery.
Batteries can be quite dangerous, especially if they are still connected to power. The electrical charge can be potentially lethal. Plus, batteries have corrosive agents that can be flammable and can damage your skin.
To be safe, you should only ever work on your battery removal when your car is turned off. You should also wear safety goggles and gloves to protect yourself.
Locate Battery
Once you are ready to start the battery removal, you must locate the battery. This should be relatively easy to find as soon as you open the hood of your vehicle.
Typically, they are bolted in place in plain sight, but sometimes they are tucked away out of sight. If you are unsure of your battery location, you can check your owner’s manual for more information.
Find the Negative and Positive Terminals
One of the most important steps for removing your car battery identifying the negative and positive terminals of your car battery. These are typically marked with positive and negative symbols.
They may also have a cap or cover, with the negative terminal having a black cap and the positive terminal having a red cap.
Get the Right Size Wrenches
Next, you need to get the right size socket on your wrench to loosen the nuts on the terminals. You might need a few different sizes to be able to complete this job.
The size of the wrench you need may also depend on how much space you have to work. If you don’t have much space to maneuver the wrench, you may need to find one that is a bit smaller.
In most vehicles, you will need a 10-millimeter wrench to remove the bolts, but an adjustable wrench would work as well.
Unbolt Cables
Once you have the right wrenches for the job, you can begin to unbolt the cables. This is one of the more dangerous parts of battery removal, so you must make sure your car ignition is turned off.
You can start by removing the nut that holds the cable on the negative terminal. In many cases, you will need to wiggle or twist it to fully remove it. Once you remove the negative cable, make sure it is pushed out of the way so there is no chance of it interacting with the positive cable or battery terminal.
Next, you can remove the positive cable.
While you are loosening the cables from your battery, make sure you never touch your wrench to both terminals at the same time. If this happens, the residual electricity from the battery will flow through the wrench and can cause an electrical shock.
Remove the Hold Down Clamp
Finally, you can remove the hold-down clamp once your battery cables have been completely disconnected. In most vehicles, the batteries are secured by a clamp or a bar that runs across the top of the battery.
It locks the battery into place on the tray that it sits on and makes it impossible to remove the battery without first removing this clamp.
You will need a socket wrench to remove this hold-down clamp. Once it is loosened and removed, you can carefully lift the battery out of your vehicle.
As you remove the battery, you must be careful to keep it level. Otherwise, the battery acid inside can slosh around and can cause itching and pain on your skin. Similarly, you must store your old battery on a flat surface.
If you are replacing your battery immediately, you can use a wire brush and a shop towel to clean the cable connectors and remove any corrosion that remains. You can also use your anti-corrosion grease or anti-rust spray to prevent new rust from forming on your new battery.
Once you have removed your battery, you can start on your battery replacement.
