Now locate the car battery at one corner of the engine bay. The car battery might present at one of the sides of the bumper or rear the windshield. Note that two cables would be attached. A brand new car might have a car battery wrapped in the plastic cover so, find it there.
Disconnect the cables
Disconnect the cables but always make sure to disconnect the negative cable first. This is so to bypass the electric shock. With the black appearance, the negative cable imprint (-) on it. If covered with a plastic sheet, remove it first and lose the cable with the help of a wrench. Finally, separate the cable from the terminal. according to your type, use 7 mm, 8 mm, 10 mm or 13 mm wrench to remove the cable.
Make sure that negative cable should not touch with the metal. To discourage this chance, a good idea is to tie the cable with the engine bay.
Now, its turn to remove the positive cable. Usually red in color, positive cable imprints (+) on it. Separate the plastic cover, if present, and remove the cable off from the terminal with the help of a wrench. Tie the cable with the engine bay with help of a clamp.
Be careful! the positive and negative cable should not touch each other or with anything made of metal. Because it may cause rapid shock and leads to destruction.
Remove the battery from the car
Examine carefully that either the car battery is secure by bracket. Remove all fasteners that usually keep the battery in place. You may need specific tools like extension bar, socket, and socket wrench. Once you have disconnected all connectors, pull the battery out and place it at the concrete surface (if possible).

Always double-check that battery is perfectly secure in bracket hence, it can not vibrate while driving.
Don’t spray the lubricant to the terminals or other parts of the vehicle.
Reconnect the cables
Connect the positive terminal first to the engine bay, be sure not to touch the metal across its ends. Tight the cable to its respective terminal with the help of a wrench. Repeat the same steps to connect the negative terminal.
