Disconnect the Positive Terminal:
After disconnecting the negative terminal, proceed to the positive terminal. Loosen the nut on the positive cable and pull the cable away from the battery. Always follow the negative-first protocol to prevent short circuits.
Remove the Hold-Down Bracket:
Remove the battery hold-down bracket that keeps the battery secure. This involves locating the screws or clamps, unscrewing them with a wrench, and taking the bracket off. This step ensures that the battery can be lifted out freely.
Lift Out the Battery:
Finally, safely lift out the battery using both hands. Batteries can be heavy, so exercise caution and use proper lifting techniques to avoid injury. Ensure that you handle the battery in an upright position to prevent leaks.

Following these detailed steps will help you successfully remove and prepare for a new battery installation in your 2010 Mazda.

How Do You Properly Disconnect the Battery Cables?

To properly disconnect battery cables, follow these steps: always turn off the vehicle and remove the key, then start with the negative cable before the positive one, and finally secure the cables away from the battery terminals.

Turn off the vehicle: Ensure the ignition is off to prevent any electrical shorts or shocks while disconnecting the battery. This is crucial for safety.
Remove the key: Take the key out of the ignition or ensure that the vehicle is powered off completely. This helps to eliminate any current running through the electrical system during the disconnection process.
Disconnect the negative cable first: Locate the negative terminal on the battery, often marked with a minus (-) sign or black color. Use a wrench to loosen the bolt securing the negative cable. Removing this cable first reduces the risk of accidental short circuits.
Disconnect the positive cable: After the negative cable is safely detached, locate the positive terminal, which is typically marked with a plus (+) sign or red color. Again, use a wrench to loosen the bolt on the positive cable and remove it.
Secure the cables: After both cables are disconnected, ensure they are placed away from the battery terminals to prevent accidental reconnection. You can tuck them away or cover them with non-conductive material to enhance safety.

Following these steps minimizes the risk of electrical shock or damage to the vehicle’s electrical system.

What Precautions Should You Take Before Removing the Battery?

Before removing the battery, take the following precautions to ensure safety and prevent damage.

Gather necessary tools.
