1. Gather the necessary materials.
- A new battery that is the correct size and type for your vehicle.
- A 10mm wrench or socket.
- A pair of gloves to protect your hands.
- Safety goggles to protect your eyes.
- A battery brush or wire brush to clean the battery terminals.
- A can of battery cleaner or a mixture of baking soda and water.
2. Park your car in a safe location and turn off the engine.
Make sure the car is in Park (for automatic transmission) or first gear (for manual transmission) and the parking brake is engaged.
3. Open the hood of your car.
Refer to your vehicle owner’s manual for instructions on how to do this.
4. Locate the battery.
It is usually in the engine compartment, near the front of the car. The battery is a black rectangular box with two metal terminals, one positive (+) and one negative (-).
5. Disconnect the negative terminal.
Use the 10mm wrench or socket to loosen the nut that holds the negative terminal cable to the battery. Be careful not to touch the positive terminal with the negative terminal cable, as this can cause a spark.
6. Disconnect the positive terminal.
Use the 10mm wrench or socket to loosen the nut that holds the positive terminal cable to the battery. Be careful not to touch the negative terminal with the positive terminal cable, as this can cause a spark.
7. Remove the old battery.
Lift the old battery out of the battery tray. Be careful not to drop it, as this can damage the battery.
8. Clean the battery terminals.
Use the battery brush or wire brush to clean the battery terminals until they are shiny. This will help to ensure a good electrical connection.
9. Apply a thin coat of battery grease.
Apply a thin coat of battery grease to the battery terminals to help protect them from corrosion.
10. Install the new battery.
Place the new battery in the battery tray and make sure it is seated properly.
11. Connect the positive terminal.
Use the 10mm wrench or socket to tighten the nut that holds the positive terminal cable to the battery.
12. Connect the negative terminal.
Use the 10mm wrench or socket to tighten the nut that holds the negative terminal cable to the battery.
13. Close the hood of your car.
14. Start your car.
Turn the key in the ignition and start your car. If the car starts, the battery has been successfully replaced.
15. Check the battery voltage.
Use a voltmeter to check the battery voltage. The voltage should be between 12.6 and 14.7 volts. If the voltage is too low, the battery may need to be recharged or replaced.
