Preparation is Key
Before you start replacing the car battery, there are a few things you need to do to prepare:
Make sure you have a replacement battery that is compatible with your Mazda 3. You can find this information in your owner’s manual or on the manufacturer’s website.
Disconnect the negative (black) cable from the battery. This is an important safety precaution to prevent any accidental short circuits.
Locate the battery. In a Mazda 3, the battery is usually located in the trunk, on the driver’s side. You may need to remove some trim panels or other components to access it.
Take note of the battery’s positive (red) cable. This cable is usually attached to the battery terminal and should be disconnected before you start working on the battery.
