1. Gather Your Supplies:
* New Battery: Make sure you get a battery with the correct group size for your Stratus. Check your owner's manual or the sticker on your old battery for this information. Auto parts stores can help you find the right one.
* Wrench: You'll likely need a wrench to remove the battery terminals. A 10mm or 13mm wrench is usually sufficient, but check your car first.
* Safety Glasses: Protect your eyes from acid splashes.
* Gloves: Protect your hands from acid and potential corrosion.
* Baking Soda and Water: Have a mixture ready to neutralize any battery acid spills.
* Optional: Battery Terminal Cleaner: This can help ensure a good connection with the new battery.
2. Preparation:
* Park on a level surface: This prevents accidental rolling.
* Turn off the car: Ensure the ignition is off and the key is removed.
* Disconnect the Negative Terminal First: Locate the negative (-) terminal (usually black). Loosen the nut or bolt and carefully disconnect the cable. Set the cable aside, away from the battery.
* Disconnect the Positive Terminal: Next, disconnect the positive (+) terminal (usually red) in the same way.
3. Remove the Old Battery:
* Secure the battery hold-down: Some Stratus models have a clamp or strap holding the battery in place. You may need to loosen or remove this before lifting the battery out.
* Lift out the battery: Carefully lift the old battery out of the tray. It may be heavy, so be mindful of your back.
4. Install the New Battery:
* Install the new battery: Place the new battery in the tray, ensuring it's seated correctly.
* Reconnect the Positive Terminal: Attach the positive (+) cable to the positive terminal.
* Reconnect the Negative Terminal: Attach the negative (-) cable to the negative terminal.
5. Clean Up and Test:
* Check connections: Ensure all terminals are securely fastened.
* Clean up any spills: If any battery acid spilled, neutralize it immediately with your baking soda and water mixture.
* Start the car: Turn the ignition key to start the engine. If it starts, you've successfully replaced the battery.
Important Considerations:
* Acid Spills: Battery acid is corrosive. If you spill any, neutralize it immediately and thoroughly clean the area.
* Safety First: Always wear safety glasses and gloves when working with a car battery.
* Electrical Components: Be careful not to touch any other metal parts of the car while working on the battery. A short circuit could damage your car's electronics or injure you.
* Disposal: Properly dispose of your old battery at a recycling center or auto parts store. Don't throw it in the trash.
If you're uncomfortable performing this task yourself, it's best to take your car to a qualified mechanic or auto parts store for a professional battery replacement. They can handle it quickly and safely, and often offer testing to ensure your charging system is working correctly.
