Procedure

Follow these step-by-step instructions to learn how to replace the battery on a Hyundai Elantra.

1. Turn off the engine. Remove the key from the ignition. Engage your parking brakes.

2. Open the hood by pulling on the hood release lever under the dashboard.

3. 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 to access the battery.

   

4. Disconnect the battery cables. Use a socket and ratchet handle to loosen the 10 mm nut in the negative (-) terminal. You will notice a (-) minus symbol or the words NEG / NEGATIVE stamped on the battery near the negative battery post. If the cable resists coming off the battery terminal, try twisting the clamp, then remove it.

5. Next, repeat the process for the positive (+) terminal.

6. Remove the battery bracket. 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.

   

   Remove the old battery. 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.

7. If the old battery was fitted with an insulation sleeve, remove it from the 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.
8. 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.

9. Clean battery terminal and clamp. Before reconnecting the cables, clean the terminals using the battery post brush tool.

   

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

    it.

11. 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 ensure they are secured on the battery post. This guide applies to model years 2011, 2012, 2013, 2014, and 2015.
