How to Disconnect a Car Battery

How to Disconnect a Car BatteryAs you prepare to disconnect your car battery, first make sure the car is turned off and safely parked where you’ll have space to work. Then, gather all your tools, including the following:

  • Owner’s manual
  • Wrench set (socket and/or open end)
  • Protective eye goggles (recommended)
  • Gloves (recommended)

The owner’s manual will help guide you to the battery’s location, as some can be difficult to find. If the battery is located under the hood, be sure to safely prop up the hood to have the best view.

Disconnecting the Battery

Once you spot the battery, use the recommended protective wear (gloves and goggles) to keep your eyes and skin safe. Look first for the negative terminal that has a minus sign on it. Remove the plastic cap and find a wrench to fit around the bolt. Then, loosen it and remove the cable. Make sure the cable does not touch the battery and is far out of reach.

Now, you’ll do the same for the positive terminal. Find the plus sign and remove the cap. Then, loosen the bolt and move the cable far out of the way.

Another important safety tip is never to rest the wrench on the battery where it could touch both the positive and negative terminals. Keep it safely out of the way to prevent any electrical shortages or sparks.

Removing the Battery

How to Disconnect a Car BatteryTo completely remove the battery, you’ll need to take some extra steps to unbolt the clamp. Grab your socket wrench and undo the bolts. Then, you should be able to lift out the battery.

Note: Car batteries are heavy and can weigh 30 pounds or more. If you this is too heavy for you, have one of our technicians do the removal instead.

Signs You Need a New Car Battery

You might notice some signs of wear as your battery ages. For one, it may become more difficult to start your car. In addition, you may hear strange engine noises or see the check engine light illuminated on the dashboard. If you hear or see any of these symptoms, schedule an appointment to have the battery checked.

It’s also possible to conduct some inspections yourself. Once you locate the battery, check for any leaks, corrosion, or bloating. There may also be a strong odor, which further points to an issue with the battery and the need for replacement.

If you don’t see these signs, check instead the battery fluid level. Ensure it’s at the right amount or add more to fix the problem.
