A car battery isn’t like a regular household battery you might have in your TV remote and it requires a special approach when disposing of one.

The average car battery contains things like acid and lead so it’s not to be dealt with lightly.

In addition to the dangerous contents, a car battery can potentially shock someone or even explore. The battery acid can leak out through holes or when it’s tipped over and burn the skin, or lead to blindness in severe cases.

  2. Find where the positive and negative terminals are on the battery. The positive will be marked with a “+” and the negative a “-“. Remove the plastic caps that are covering these terminals so you can get access to the battery and remove it from the vehicle, as well as the cable clamps that have to be disconnected.
  3. Select the wrench or wrenches that will fit the battery, with sometimes just an open-ended wrench being all you need. The wrench will be used to disconnect the cables that keep the battery attached to the car, so it has to be the right size to maneuver the bolt from them.
  4. Go ahead with your protective gear, including putting on gloves and wearing long sleeves. Double-check that the car’s ignition is off and the key is out.
  5. Unbolt the negative battery cable first and then lift it off to disconnect it. Remove it from the area completely. You don’t want the wrench to be touching both negative and positive terminals otherwise it can create a spark. Then, do the same to unbolt remove the positive cable.
  6. Finally, remove the clamp that holds the battery in place inside the tray. Pull the battery out and store it upright before moving onto the next part.
