Tools You'll Need:
* Wrench (usually 10mm or 13mm, check your owner's manual) to loosen the battery hold-down clamp.
* Socket wrench and socket (if the hold-down is a bolt instead of a clamp)
* Safety glasses
* Gloves (optional, but recommended)
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and turn off the engine. Ensure the vehicle is not running.
2. Locate the Battery: Open the hood. The battery is usually located in the front of the engine compartment, but its exact position might vary slightly.
3. Disconnect the Battery:
* Negative Terminal First: Locate the negative (-) terminal (usually marked with a "-" sign). Use your wrench to loosen the nut or bolt connecting the negative cable to the terminal. Carefully remove the cable.
* Positive Terminal Second: Locate the positive (+) terminal (usually marked with a "+" sign). Loosen the nut or bolt and remove the positive cable.
4. Remove the Hold-Down Clamp: There's usually a clamp or bracket holding the battery in place. Use your wrench to loosen the clamp or bolt(s) securing it. Carefully remove the clamp or bolts.
5. Lift Out the Battery: Carefully lift the battery out of the tray. It can be heavy, so be prepared.
6. Install the New Battery: Place the new battery into the tray, ensuring it sits correctly.
7. Secure the Battery: Tighten the hold-down clamp or bolts.
8. Reconnect the Battery:
* Positive Terminal First: Connect the positive (+) cable to the positive terminal and tighten the nut or bolt.
* Negative Terminal Second: Connect the negative (-) cable to the negative terminal and tighten the nut or bolt.
9. Double Check: Ensure both cables are securely connected.
10. Close the Hood: Carefully close the hood.
11. Important: After installing a new battery, you may need to reprogram your vehicle's computer system. This often involves driving the vehicle for a certain period. Consult your owner's manual for specific instructions or a qualified mechanic.
Important Considerations:
* Battery Acid: Battery acid is corrosive. Avoid getting it on your skin or clothes. If it does happen, immediately flush the affected area with plenty of water.
* Disposal: Properly dispose of your old battery at a recycling center or auto parts store. They often accept old batteries for recycling.
* Terminal Corrosion: If you see significant corrosion on the battery terminals, clean them with a wire brush and baking soda solution before connecting the new battery.
Remember, this is a general guide. Always refer to your owner's manual for specific instructions tailored to your 1999 Chrysler Sebring. If you're unsure about any part of this process, it's best to have a qualified mechanic do it for you.
