Our dedicated mechanics will get it done for you in a jiffy. We can also take care of properly recycling your old battery. Now, let’s dive into how to change a car battery so you can get back to driving around Doral, Miami, Hialeah, and Kendall.

Gather Your Supplies

The first thing you’ll need to do is gather the equipment you’ll need for the replacement. You’ll need:

  • Your new Mazda replacement battery
  • Protective gloves
  • Safety glasses
  • Ratchet with extension
  • Sockets
  • Hot water

Completely turn off your car and engage the parking brake, and you’ll be ready to go. Be sure to check your driver’s manual to see if you’ll need to input radio and navigation codes after you install the new battery. Either use a memory saver or write the codes down so you can re-enter them later. This will ensure that your radio and navigation system will continue to function properly after your battery replacement.

Step 1: Remove the Old Battery

Start by putting on your gloves and safety glasses. Remove the battery cables, but be sure to remember or label them as positive and negative; this way, you won’t mix them up later. You’ll also need to loosen the battery hold-down clamp that connects the battery to the vehicle using your ratchet and socket. Next, loosen the negative and then the positive battery terminals, and pull off the battery posts. Now, all you’ll have to do is lift the battery out of the car—use your legs, it’s heavy!

Step 2: Clean the Battery Terminals

Use a steaming hot cup of water and pour it directly onto each terminal of your old battery to remove any corrosion or sulfate power. That way, you can safely touch the battery without your protective gloves. You can also clean the battery cable connectors with a wire brush or use a battery-cleaning solution for heavier corrosion.

Step 3: Install Your New Battery

Lift your new battery into the car and attach it with the hold-down clamp. Attach the positive battery cable first, followed by the negative cable. Make sure that all connections are properly tightened; if you can move any of them at all, they’re not tight enough.

Step 4: Get Behind the Wheel!

Once you’re finished, you can close the hood and test to see if your car starts. How easy was that?!

Bring your old battery into the dealership to be recycled, and you’re good to go for a drive around Doral, Miami, Hialeah, and Kendall. Congratulations! In a few simple steps, you were able to successfully replace your own car battery. If you have any questions or if you’d rather have a professional mechanic install your battery, contact Ocean Mazda.
