1. Gather your tools:
* New battery: Make sure you get a battery with the correct group size for your Bonneville. Check your owner's manual or the sticker on your old battery for this information (e.g., Group Size 65).
* Socket wrench: You'll need a wrench to remove the battery terminal clamps. A 10mm or 13mm socket is usually needed, but double check your existing battery terminals.
* Safety glasses: Protect your eyes from acid splashes.
* Gloves (optional but recommended): Battery acid is corrosive.
* Baking soda and water (optional): To neutralize any spilled acid.
2. Disconnect the battery:
* Important: Always disconnect the negative (-) terminal first. This prevents accidental short circuits. Loosen the nut on the negative terminal clamp and remove the clamp.
* Then, loosen the nut on the positive (+) terminal clamp and remove the clamp.
3. Remove the battery hold-down:
* Most Bonnevilles have a clamp or strap securing the battery. You may need to loosen a bolt or nut to release it. Consult your owner's manual if you're unsure how to release the hold-down.
4. Lift out the old battery:
* Carefully lift the battery out of the tray. It can be heavy, so be prepared.
5. Install the new battery:
* Place the new battery in the tray, making sure it sits correctly.
* Secure the battery with the hold-down clamp.
6. Connect the battery:
* Connect the positive (+) terminal clamp first. Tighten the nut securely.
* Then, connect the negative (-) terminal clamp. Tighten the nut securely.
7. Double-check:
* After connecting the terminals, ensure all connections are secure and no wires are loose.
Important Considerations:
* Owner's Manual: Your owner's manual is the best resource for detailed instructions specific to your vehicle. It will show you exactly where the battery is located and how to access it.
* Acid: Battery acid is corrosive. Be careful not to spill any. If you do spill some, neutralize it immediately with a baking soda and water solution.
* Radio Codes: Disconnecting the battery may cause you to lose your radio presets. You may need your radio code to restore your settings. Check your owner's manual or contact your dealer for assistance.
* Electronic Memory: Some electronic systems may lose their settings.
If you're uncomfortable working on your car yourself, it's always best to take it to a qualified mechanic or auto parts store for battery replacement. They can do it quickly and safely.
