Additionally, it's highly recommended to have:
* Safety glasses: To protect your eyes from acid splashes.
* Gloves: To protect your hands from battery acid.
* Baking soda and water: To neutralize any spilled battery acid.
* A battery terminal cleaner: To ensure a good connection.
While not strictly a *tool*, having your owner's manual handy is crucial for confirming the correct size wrench and for any specific instructions or cautions related to your vehicle's battery installation.
