Turning off the engine. Remove key from ignition. Engage your parking brakes.
Open the hood by pulling on the hood release lever located under the dashboard.
All Hyundai Elantra cars have the battery located in the engine bay. Note that some models have a plastic cover above the battery. This will need to be removed in order to access the battery.
Use a socket and ratchet handle to loosen the 10 mm bolt on the negative (-) terminal. Near the negative battery post, you will notice a (-) minus symbol or the words NEG / NEGATIVE stamped on the battery. If the cable resists to come off the battery terminal, try twisting the clamp then remove it. Next, repeat the process for the positive (+) terminal.
If the battery cable still refuses to come off the terminal, you may want to use a battery terminal puller. This will help prevent damage to your battery and clamp.
Locate the battery clamp. Remove the 12 mm bolt on the battery clamp. Use a socket and ratchet to remove this bolt. Place both the hold-down device and the bolts aside.
Take the battery out of the battery tray. Batteries are heavy, so grab from the bottom using both hands. If the battery has a handle, use that instead. If the old battery was fitted with an insulation sleeve make sure to remove it from old battery and install it on the new battery. Carefully, lower the new battery on the battery tray. Pay attention to the battery +/- pole orientation. They need to be in the same location as the old battery.
Reinstall the battery bracket. Ensure that the battery does not move. Try to move the battery back and forth to ensure that the battery is secure.
Before you reconnect the cables, clean the terminals using the battery post brush tool. You can buy a new battery top post/terminal cleaning tool on Amazon for under $10.
Next, connect the positive cable and fasten the terminal bolts. Now you can reconnect the positive battery cable. Last, connect the negative battery terminal and tighten the bolt.
Ensure that all cable connections/ hold downs are properly tightened. Check the security of your battery by trying to move it back and forth.The battery cables should not move or rotate on the terminals. If your car does not start, check the battery cables to make sure they are secured on the battery post.
