Gathering Your Battery Changing Arsenal

Before you begin, make sure you have all the necessary tools. Having everything on hand will prevent interruptions and frustration. These tools are generally inexpensive and readily available at most auto parts stores.

• Battery Terminal Cleaner: Corrosion can build up on the battery terminals. A wire brush or a dedicated terminal cleaner will help ensure a good connection.
• Rags or Paper Towels: Cleaning the terminals and wiping up any spills requires absorbent materials.

Optional but Helpful Tools

• Battery Terminal Puller: This tool helps to safely remove stubborn battery terminals without damaging them.
• Memory Saver: A memory saver keeps your car’s computer settings and radio presets intact while the battery is disconnected.
• Socket Wrench with Extension: In some vehicles, a socket wrench with an extension may offer better access to the battery hold-down clamp.
• Dielectric Grease: Applying dielectric grease to the terminals after installation can help prevent future corrosion.
