How to Remove a Car Battery

Mechanic changing car battery

You don’t have to be a mechanical genius to be a car owner in Nashville. Modern vehicles are engineered to require very little hands-on repair, which has made car ownership so much more accessible. But it’s still valuable to know some car maintenance basics, like how often you should rotate your tires when you’re driving daily in Hendersonville, or what grade of gasoline is best for your car. Knowing how to remove your car battery can be a huge help when it’s time to replace it. Save time and money by learning how to remove a car battery with Music City Autoplex.


  • Car batteries can weigh up to 40 pounds. Make sure you’re physically able to lift that much before you get started.
  • Work in a well-ventilated place so you’re not at risk of overexposure to harmful gases.
  • Prevent your battery cables from touching by holding them in place with zip ties. If they touch, they can create sparks and become a fire hazard.
  • Cover the positive cable end with a cloth once it is removed to avoid the risk of metal-to-metal contact.
  • Take off all jewelry or jackets that might have metal zippers or buttons to prevent getting a shock if they come in contact with the 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 in close proximity.
  • Take hold of the bolt head of the negative terminal with a wrench or pliers and hold it still.
  • Use other pliers or 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.
