Should you ever need to inspect your car battery or fully replace it, you’ll want to be familiar with removing car battery housing and components! In the following guide, our service center experts have outlined how to remove a car battery so whether you’re addressing your own battery issues or helping out a O'Fallon neighbor, you can be prepared to accomplish the task. Read on below to tips and tricks about removing car battery parts.

Prepare to Remove Car Battery

Batteries are packed with a current to start your Mazda, keep it running throughout Fairview, and power your entire electrical system. This amount of stored power is enough to deliver a serious shock, so proper safety precautions are in order: always turn off the car and wear insulated gloves and safety glasses when removing car battery parts. Here are other important safety tips:

  • Prevent the battery cables from touching— if they do, they will spark. Zip ties or other restraints should work just fine to safely hold them apart and out of the way.
  • Once the cables are restrained, put a cloth over the positive end of the cable to further prevent metal-to-metal contact.
  • Remove any jewelry. Again, these measures seek to avoid metal touching metal.
  • Ensure you are removing car battery components in a well-ventilated area.

Removing Car Battery

Now that you’ve taken the proper safety measures, let’s learn how to remove a car battery. Follow the steps below:

  • Locate the negative terminal, denoted by a black cover and/or a negative icon. Remove the plastic cover if necessary.
  • Secure a solid hold on of the negative bolt head with a wrench or pliers. Hold it steady.
  • Remove the nut with another wrench or pliers, then pull off the negative cable completely and secure it away from the battery as you did in the earlier steps.
  • Repeat the above step for the positive cable, taking care that the two battery cables do not touch
  • Removing car battery brackets may also be in order if your battery is secured by one. Simply unscrew the bolts that hold it.
  • Lift out the battery carefully, prepared to use some muscle as it may weigh up to 40 pounds!
