1. Safety First: Disconnect the negative (-) battery cable *before* the positive (+) cable. This prevents accidental short circuits. Use a wrench (usually 10mm or 13mm, check your size) to loosen the cable nuts. Pull the cables off the terminals.
2. Remove the Hold-Down: Most Intrepids have a clamp or bracket holding the battery in place. This will vary slightly depending on the exact trim level and options, but it's usually a simple clamp or a strap with a quick release mechanism. You'll likely need a wrench or possibly a screwdriver to remove this. Consult your owner's manual for specifics if you're unsure.
3. Lift Out the Battery: Once the hold-down is removed, carefully lift the battery out of the tray. It will be heavy, so be prepared.
4. Dispose Properly: Take the old battery to a local auto parts store or recycling center. Many stores will accept old batteries for free or a small fee, and proper disposal is crucial for environmental reasons.
Important Considerations:
* Owner's Manual: Your owner's manual will have the most accurate and detailed instructions specific to your vehicle. It's always best to consult it first.
* Cable Corrosion: You might encounter corrosion on the battery terminals. Use a wire brush or terminal cleaner to remove this before disconnecting the cables. This will improve the connection when you install the new battery.
* Eye Protection: Wear safety glasses to protect your eyes from acid splashes or debris.
* Gloves: Wearing gloves is also a good idea to protect your hands from battery acid.
Remember to reverse the steps when installing a new battery, connecting the positive (+) cable *before* the negative (-) cable. After installation, check that everything is secure and start your car to ensure proper function.
