Tools of the Trade

Before you can install your new battery, you’ll need a few supplies. If you don’t have what you need, feel free to get in touch with our parts department. Here are the tools you’ll need:

  • Wrenches
  • Battery cleaning solution
  • New battery
  • Wire brush
  • Pliers
  • Anti-corrosion spray are all essential
  • Rubber work gloves

If this is your first time installing a battery or you need to refresh your memory, it’s always a good idea to have your owner’s manual on hand! This will help you find exactly where your battery is located, as well as what type of replacement you need.

Battery Installation Steps

Now that you have your supplies in hand, it’s time to learn how to install a car battery.

  1. Turn your car off and engage the parking brake for safety.
  2. Open the hood and locate the battery. Put on your work gloves.
  3. Loosen the nut connecting the negative cable (black) from the terminal using the wrench. Twist and pull the cable off carefully to avoid damage.
  4. Repeat step 3 with the positive cable (red). 
  5. Loosen the battery hold-down clamp that keeps the battery in place. Remove the clap.
  6. Use both hands to get a good grip on the battery and remove it.
  7. Clean up any corrosion in the battery tray with a battery cleaning solution. Use your wire brush and clean the battery cable connectors as well.
  8. Grab the new battery with two hands and place it in the tray. Tighten the hold-down clamp.
  9. Spray your anti-corrosion spray on the terminals of the new battery. Though optional, this can extend the lifespan of your battery.
  10. Connect the red cable to the positive terminal and then the black cable to the negative terminal. Double-check your work to ensure everything is secure.
  11. Start the car and enjoy your new battery!
