How to change a car battery?

Changing a car battery requires you to wear protective gear, secure the vehicle, and cover the disconnected cables to prevent accidental sparks.

• Ensure that the car is locked and parked in a secure area. Also, if parked in a garage, ensure the garage door is open. Assume the vehicle is in park (or first gear with a manual transmission), with the back wheels chocked and the parking brake engaged.
• Depending on the car, open the trunk or hood. If the battery’s position is unclear, check the owner’s manual for its location.
• Then remove the battery hold-down clamp.
• First, unplug the negative cable with a wrench. Then disconnect the positive cable. Always remember that positive is red and negative is black.
• Lift the battery out of the way using the strap, but watch out for any acid spills.

• Place your replacement battery in its designated location. Ensure the battery is firmly positioned, and pay attention to where each terminal is connected.
• If necessary, reinstall the battery’s securing posts.
• The positive terminal has to be reconnected and tightened before the negative terminal. The cables must be immovable and tightly fastened to the terminals. Check again to ensure that the position of the new battery matches the red and black terminals. Consider applying protective felt washers or battery anti-corrosive protection gel to both terminals before reconnecting them.
• Once you have tightly fastened the cables, start the car to ensure everything is in working order. If everything is okay, it should start immediately.
• Close the hood once you finish the replacement process and remove all of your tools from the engine compartment.
