A Step-by-Step Guide to Safely Replacing Your Car Battery

Have you ever found yourself in a situation where you turn the ignition key, and your car doesn't start? 

It's a frustrating experience, and more often than not, a dead battery is the culprit. While this might seem like a daunting problem, replacing a car battery is a task you can handle at home with a little guidance and preparation. 

At EDS Parts we want to help you get back on the road! 

This comprehensive guide will walk you through the process step by step, ensuring you can get back on the road as soon as possible.


Before you begin, it's essential to consult your car's owner's manual. 

This handy book is like a treasure map, guiding you through the unique layout and specifications of your vehicle. 

It will provide specific instructions related to your car's make and model, helping you understand where everything is and how it works.

Next, gather all the tools you'll need before starting. 

This includes a wrench to loosen the nuts and bolts, a wire brush for cleaning the battery terminals, and a new battery. It's also a good idea to have a pair of gloves and safety glasses on hand to protect your hands and eyes during the process.

Disconnecting the old battery

Start with the negative battery terminal - it's the one marked with a minus sign.

Using your wrench, loosen the nut and disconnect the terminal. It's crucial to start with the negative terminal to avoid any electrical short circuits. 

Once you've safely disconnected the negative terminal, move on to the positive terminal, marked with a plus sign. Loosen the nut and disconnect it. Now, the battery is free from the car's electrical system.

Removing the old battery

Your battery sits in a special tray designed to hold it securely in place. 

There's a nut holding it in place. Using your wrench, loosen this nut, and you can lift the battery out. Remember, car batteries are heavy, so lift with your knees, not your back, to avoid injury.

Cleaning the battery terminals

With the battery out of the car, it's time to clean the battery terminals. 

Here’s where your friends at EDS Parts come into play. 

There’s many times where you may find that your battery terminals need replacing.

Over time, these terminals can become dirty or corroded, which can affect the performance of your battery. 

At EDS we have terminals for many car builds, including Nissan, Toyota, GM, Silverado’s, and many more.

To maintain upkeep of terminals, you can also look into anti-corrosion spray. Keeping them free of corrosion is key to a healthy battery with an extended lifetime.

Installing the new battery

Now, it's time to install the new battery. Place it in the battery tray and tighten the nut to hold it in place. Connect the positive terminal first, then the negative terminal. Make sure the connections are tight - a loose connection can lead to problems down the line.

Final checks

Before you close the hood and start your car, take a moment to double-check everything.

Is the battery secure in its tray? 

Are the terminals clean and tightly connected? 

If your car has plastic covers for the terminals, replace them now. 

These covers help protect the terminals from dirt and corrosion, so they're important to keep in place.

Starting your car

Now, take a deep breath and start your car. If you've followed these steps correctly, your car should roar to life with the turn of the key. Congratulations! You've just replaced your car battery.

Maintenance tips

Remember, regular cleaning and maintenance can help your battery last longer, so keep that wire brush handy and check your battery regularly. If you notice any signs of corrosion or damage, it might be time for another replacement.
