How to Remove a Car Battery the Right Way

Auto Mechanic Replacing Car Battery


If you aren’t familiar with much of what’s going on under your car’s hood, we understand! Not everyone has that knowledge, and that’s why we’re here to help you understand more about what makes a vehicle work, and more importantly, what you need to know to safely own and operate your motor vehicle!

Your vehicle’s battery is one such under-the-hood component, and its job is to provide the power to start your car, help keep it running, and power all of the electrical components you enjoy on your Kearny commutes. On this page, you’ll learn how to remove a car battery the right way! If you have any follow-up questions, feel free to reach out to us online.

Safely Removing a Car Battery – Preparing to Work

Before you learn how to remove a car battery, you’ll want to prepare for the job. Under normal, safe operating conditions, with a non-faulty battery, there’s not really much danger involved in installing or removing a car battery. That being said, there could be something physically wrong with your battery that you aren’t seeing on the surface, and handling it should always involve safety equipment like shop glasses, gloves, and some durable clothing.

Removing jewelry and working in a well-ventilated area are also both smart ideas. When it comes to the exposure to chemicals, fumes, and other hazards of a potentially faulty battery, it’s of course, better to be safe than sorry.

Steps for Removing Car Battery – DIY Automotive Tips

Once you’ve done your due diligence to ensure your safety, as well as the safety of those around you, follow the steps listed below to safely remove your vehicle’s battery:

  • Find the negative terminal. It should have a black plastic cover or a minus sign and will be located either on the post or nearby.
  • Take hold of the bolt head of the negative terminal with a wrench or pliers and hold it still.
  • Use other pliers or a wrench to remove the nut, then pull off the negative cable and secure it away from the battery.
  • Repeat the above step for the positive cable, taking care that the two battery cables do not touch
  • If the battery is held by a securing bracket, use your pliers or wrench to take out the screws and bolts that hold it in place.
  • Lift the battery straight out of the bracket. Keep in mind that it may weigh up to 40 pounds.

Car Battery Voltage & DIY Battery Testing

If you’re fortunate enough to own a battery testing kit or a simple volt-meter, you may want to conduct a battery output test. If your charged battery is producing the proper amount of voltage, you should see a reading of around 12.6 volts or higher. When the engine is running and the alternator is cycling power through the battery, it should bump up that voltage to about 13.7 to 14.7 volts.

Of course, if you don’t own the tools for testing your battery, you’re more than welcome to rely on the assistance of our Beatrice area-local automotive service experts – including tenured mechanics and knowledgeable, trustworthy service advisors. Battery tests are a fairly inexpensive diagnostic and are often included in the scope of other general vehicle services and inspections! Contact our service center for more information!
