1. Gather Your Tools and Materials:
* New battery: Make sure you get the correct size and type (group size) for your Bonneville. Check your owner's manual or the old battery for this information. Auto parts stores can help you find the right one.
* Wrench (or socket wrench): You'll need a wrench that fits the battery terminal nuts (usually 10mm or 13mm). A socket wrench is generally easier to use.
* Safety glasses: Protect your eyes from potential acid splashes.
* Gloves (optional but recommended): Protect your hands from battery acid.
* Baking soda and water mixture (optional): To neutralize any spilled battery acid.
2. Prepare the Vehicle:
* Park on a level surface and engage the parking brake.
* Turn off the vehicle and remove the key from the ignition.
* Locate the battery: It's typically under the hood, but sometimes it might be in the trunk (less common on Bonnevilles). Consult your owner's manual if you can't find it.
3. Disconnect the Battery:
* Disconnect the negative (-) terminal FIRST. Loosen the nut and carefully remove the cable from the terminal post.
* Disconnect the positive (+) terminal NEXT. Loosen the nut and remove the cable. It's crucial to disconnect the negative terminal first to prevent short circuits.
4. Remove the Old Battery:
* There might be a hold-down clamp or bracket securing the battery. Loosen this clamp using the appropriate wrench.
* Carefully lift the old battery out of the tray. It might be heavy, so be prepared.
5. Install the New Battery:
* Place the new battery in the tray, ensuring it's seated correctly.
* Tighten the hold-down clamp or bracket.
* Connect the positive (+) terminal FIRST. Attach the cable to the terminal post and tighten the nut securely.
* Connect the negative (-) terminal NEXT. Attach the cable to the terminal post and tighten the nut securely.
6. Clean Up and Double-Check:
* Clean any spilled battery acid immediately with the baking soda and water mixture. Neutralizing acid is important to prevent corrosion.
* Double-check that both terminals are securely connected.
* Start the vehicle to ensure the new battery is working correctly.
Important Considerations:
* Battery acid is corrosive. Handle with care and avoid contact with skin or eyes.
* If you are unsure about any step, consult a qualified mechanic. This is a relatively simple task, but errors can lead to damage or injury.
* Dispose of the old battery properly. Most auto parts stores will recycle them for free.
This guide provides a general overview. Specific details might vary slightly depending on your vehicle's exact model and year. Always refer to your owner's manual for the most accurate instructions and diagrams.
