Essential Tools for a Car Battery Replacement

Changing a car battery isn’t rocket science, but it does require the correct tools. Having these on hand before you start will make the process smoother and prevent any unexpected hiccups.

Wrench (es): The most crucial tool. You’ll need a wrench (or sometimes two) of the correct size to loosen the nuts and bolts holding the battery clamps and battery hold-down. Sizes typically range from 10mm to 13mm. Having both a socket wrench and an open-end wrench can be beneficial for tight spaces.
Battery Terminal Cleaner: Corrosion on battery terminals can hinder the electrical connection. A wire brush or a dedicated battery terminal cleaner will help remove this buildup and ensure a solid contact.
Gloves: Battery acid is corrosive and can irritate your skin. Wearing gloves will protect your hands during the process.
Safety Glasses: While rare, battery acid can splash. Safety glasses offer an extra layer of protection for your eyes.
Rags: Cleaning the battery terminals and surrounding area is essential. Rags will come in handy for wiping away grime and any spilled acid (neutralized with baking soda).
