Tips for safety before you remove the battery

Before you disconnect the battery from your car, here are some safety tips.

  • Battery storage can cause a slight shock and may give rise to electric charges if they are not treated properly. Be sure to remove any jewelry, such as rings, watches, bracelets, from the battery before you disconnect it. It can lead to an electric shock if the battery is in direct contact with any metallic part.
  • The battery removal should always be done outdoors as acids can release dangerous gasses. Your exposure to hazardous gases will be minimized if the environment is open.
  • You must ensure that the work area is dry. Avoid working in damp areas or with water near your work area.
  • You may need to reset the settings on the radio or clock by removing the terminals. To unlock your radio code, you will need the radio code. Although you could add some power to your system and replace the battery, this is not recommended. It can cause serious damage and can also pose a danger.

Open the hood if your car's battery is under your car. Use the rod to keep the hood standing in its place and then look for the battery’s negative terminal. It may be covered in a black material and have a "-" sign to indicate that the terminal is negative.
Locate your car battery with the help of the owner’s manual. Sometimes it’s located in the trunk or under a seat.

4. Remove the negative terminal from the battery

It is important that you always take out the negative battery terminal before the positive one. This will reduce the chance of sparks that could cause the battery to explode.
The wrench can be used to remove the nut holding the terminal. You can loosen the terminal by using your hand, but be sure to use safety gloves.
Although it might seem difficult to locate the proper size socket wrench for you, once you find it, slowly turn the screw counterclockwise until it loosens. You should keep the nut secure.

5. The positive terminal should be disconnected from the battery

Plus Terminal

Follow the same procedure for the positive terminal once you have removed it. Do not let the positive terminal come into contact with any metal part on the car as there is some charge left in the system and in case of contact, the car’s electrical circuit can get disturbed.

6. Locate the battery strap or bracket and take it out

Car Battery Bracket

Most car batteries are secured in their place using a bracket or some other metal device. You will need to remove the bracket or strap in order to get rid of your battery. You will find the bracket holding your battery in place if you have a car with one.

• Gloves
• Petroleum jelly
• Baking soda
• Water
• Toothbrush
• Cleaning cloth

It is easy to make the cleaner. Simply mix one teaspoon of baking soda and one cup of water. Mix it thoroughly. Then, use the toothbrush to clean the terminals. It may take some effort to get rid of the grime and dust.

Thoroughly scrub the terminals until any dirt, dust, or other debris is gone. After removing the corrosion, spray some water on the terminals. Then wipe them gently with a damp cloth. Apply petroleum jelly, which provides lubrication to the terminals and helps prevent further corrosion.

Note: To ensure that the battery is clean and safe, you should first inspect it for any signs of damage such as a leak, swelling or visible damage. Cleaning the terminals is not possible if the battery has been damaged. You will need to buy a replacement battery.
