Changing your car battery might seem daunting, but with the right tools, it’s a straightforward task you can handle yourself. Before you start disconnecting anything under the hood, gathering the necessary tools will make the process smoother and safer.
If you’re planning to clean any corrosion from your battery terminals, having a baking soda and water solution ready is a smart move. This mixture helps neutralize battery acid and clean up corrosion effectively. Make sure you have a brush handy to apply it.

To disconnect the battery cables, you’ll need wrenches to loosen the nuts and bolts securing them to the battery terminals. A crescent wrench, adjustable wrench, vise pliers, or a socket wrench will work. Common socket sizes for battery terminals are 10 mm or 12 mm (approximately 0.4 or 0.5 inches). It’s useful to have a pair of adjustable pliers to hold the bolt head steady while you loosen the nut with your wrench.
Don’t be surprised if you need a hammer. Sometimes, battery terminal cables can be stubbornly stuck to the terminals due to corrosion or tight fitting. A gentle tap with a hammer can help loosen a cable that’s refusing to budge. Remember to tap gently and avoid forceful hammering to prevent damage.
Investing in a dedicated battery terminal cleaner is highly recommended. This inexpensive tool is specifically designed to remove corrosion from both the battery posts and the inside of the terminal clamps. Using a battery terminal cleaner ensures a clean and solid connection with your new battery, improving performance and longevity. Alternatively, a narrow metal wire brush can also be used to scrub away corrosion.
To prevent future corrosion, consider using a corrosion protector spray. Applying this spray to your battery terminals after cleaning and reconnecting them creates a protective barrier against moisture and air, which are the primary causes of corrosive sulfate buildup.
Safety should always be a priority when working with car batteries. Wear sturdy gloves and safety goggles to protect your skin and eyes from battery acid and debris. Accidental splashes of battery acid can cause burns, and loose debris can be harmful to your eyes.
Finally, keep some rags or cloths on hand to wipe away dirt, grease, or spills. A plastic container or toolbox is also useful for keeping your tools organized and within reach.
With these tools gathered, you’ll be well-prepared to safely and effectively remove your car battery. Remember to always disconnect the negative terminal first and reconnect it last to prevent electrical shorts.
