1. Gather Your Supplies:
* New battery: Make sure you get a battery with the correct group size for your Stratus. This information is usually found on the old battery or in your owner's manual. Auto parts stores can help you find the right one.
* Wrench (or socket wrench): You'll need a wrench to remove the battery terminal clamps. A 10mm or 13mm wrench is usually sufficient, but check your old battery's terminal size to be sure.
* Safety glasses: Protect your eyes from acid splashes.
* Gloves: Protect your hands from battery acid.
* Baking soda and water solution: Have this ready to neutralize any spilled battery acid.
* Optional: Battery terminal cleaner: This can help ensure good contact with the new battery.
2. Preparation:
* Park on a level surface: This prevents accidental rolling.
* Turn off the vehicle: Completely turn off the ignition and remove the key.
* Locate the battery: It's usually located under the hood, but sometimes in the trunk on some models, though less common for a 2002. Check your owner's manual if you are unsure.
* Disconnect the negative terminal first: Use your wrench to loosen and remove the clamp from the negative (-) terminal (usually black). Set the clamp aside, away from the battery. This prevents short circuits.
3. Removing the Old Battery:
* Disconnect the positive terminal: Remove the clamp from the positive (+) terminal (usually red). Set the clamp aside, away from the battery.
* Remove the battery hold-down: There's typically a clamp or bracket holding the battery in place. This usually involves loosening a bolt or nut, sometimes more than one. Consult your owner's manual for specific instructions if needed.
* Lift out the old battery: Carefully lift the battery out of its tray. Be mindful of the weight and any spilled acid.
4. Installing the New Battery:
* Clean the battery terminals: Use a battery terminal cleaner or a wire brush to clean any corrosion from the terminals and the battery tray.
* Install the new battery: Carefully place the new battery into the tray.
* Attach the hold-down clamp: Secure the new battery in place using the hold-down clamp.
* Connect the positive terminal: Attach the positive (+) clamp to the positive (+) terminal.
* Connect the negative terminal: Attach the negative (-) clamp to the negative (-) terminal.
5. Cleanup and Safety Check:
* Clean up any spills: If any battery acid spilled, neutralize it immediately with the baking soda and water solution.
* Double-check connections: Ensure both terminals are securely fastened.
* Start the vehicle: Turn the ignition key to start the vehicle. If it doesn't start, double-check your connections.
Important Notes:
* Battery acid is corrosive: Avoid contact with skin and eyes. If contact occurs, flush the area with plenty of water and seek medical attention if necessary.
* Consult your owner's manual: Your owner's manual will provide specific instructions and diagrams for your 2002 Dodge Stratus.
* If you are unsure about any step, seek professional help: Taking your car to an auto parts store or mechanic is always an option.
By following these steps carefully, you should be able to successfully replace the battery in your 2002 Dodge Stratus. Remember safety first!
