01Step 1: Prepare the necessary tools

  • Before starting the battery replacement process, gather the following tools:
  • Safety goggles
  • Gloves
  • Adjustable wrench
  • Battery cleaning brush
  • Battery terminal cleaner
  • Wire brush or sandpaper
  • Make sure you have these tools on hand before proceeding.

02Step 2: Turn off the engine and disconnect the battery

  • Park the car in a safe and well-ventilated area. Turn off the engine and engage the parking brake.
  • Locate the car battery. It is usually under the hood, but in some vehicles, it may be in the trunk or under the rear seat.
  • Put on the safety goggles and gloves for protection.
  • Using the adjustable wrench, loosen the nut on the negative terminal of the battery first. The negative terminal is usually marked with a minus (-) sign or colored black. Carefully disconnect the cable from the terminal.
  • Repeat the same process for the positive terminal, which is usually marked with a plus (+) sign or colored red.
  • Once both terminals are disconnected, carefully lift the battery out of its compartment and place it in a safe location.

03Step 3: Clean the battery terminals

  • Inspect the battery terminals and cables for any corrosion or dirt buildup. If necessary, use a battery cleaning brush to remove any dirt or debris.
  • To clean the terminals, dip the battery terminal cleaner in a mixture of baking soda and water. Scrub the terminals thoroughly to remove any corrosion.
  • After cleaning, rinse the terminals with water to remove any residue.
  • If the battery terminals are heavily corroded, you can use a wire brush or sandpaper to clean them further.

04Step 4: Install the new battery

  • Take the new battery and carefully place it into the battery compartment, making sure it is secure.
  • Connect the positive terminal first. Slide the positive cable onto the terminal and tighten the nut using the adjustable wrench.
  • Repeat the same process for the negative terminal. Slide the cable onto the negative terminal and tighten the nut.
  • Make sure both terminals are securely connected and there is no movement.
  • Double-check all connections to ensure they are tight and secure.

05Step 5: Test the new battery

  • With the new battery installed, start the engine and check if everything is working properly.
  • Turn on the headlights, radio, and other electrical components to make sure they are functioning correctly.
  • If everything is working as expected, congratulations! You have successfully replaced your car battery.
  • If you encounter any issues or the car does not start, double-check the connections and consult a professional if needed.
