How to replace the battery in a Ford Focus 2014-2018?

Most people know that a car battery is not something you want to be without. A car battery powers the electrical systems of your vehicle, including the starter motor and all lights on the dashboard. When a car battery dies, it can be difficult for you to start your engine or even turn on your headlights. For your Ford Focus 2014-2018 model, battery replacement is a pretty straightforward process that can be completed in less than thirty minutes.

Before you begin, always wear some protective gear, including safety goggles and gloves. Safety should be the top priority when replacing your car's battery, so make sure you are keeping yourself safe.

Step 1: You'll need to locate where your battery is in your car. The battery is often located in the engine bay, but this can vary depending on which vehicle you have and what year it was built.

Step 2: Find where the negative battery cable is and loosen its nut. Disconnect the negative lead terminal and insulate it or wrap it with electrical tape to avoid accidental reconnection.

Step 3: Remove the mass airflow wiring connector and unplug the wiring loom.

Step 4: Disconnect the vacuum hose from the side of the airflow outlet, loosen the hose retaining clamp and remove the outlet hose.

Step 5: Release the pipe retainer tab and remove the rubber strap. Grasp and lift up the air cleaner box and set it aside.

Step 6: Lift up the front cover panel of the battery and slide it forward.

Step 7: Loosen the clamp nut of the positive lead and detach the terminal and make sure that it's placed away from the battery.

Step 8: Unclip the wiring plug and the wiring loom at the front of the battery so you can open the front panel of the battery tray.

Step 9: Remove the retaining bracket on top of the battery by loosening its nuts, slide the battery a bit forward and detach the wiring sensory plug.

Step 10: You may disconnect the negative lead terminal from the old battery if required. Then refit the negative lead terminal to the new battery and make sure you tighten the nut up well. You can apply a little amount of petroleum jelly to insulate the negative terminal to help prevent corrosion.

Step 11: Now, you can refit your car battery back into place, reconnect the sensor wiring that was disconnected just a while ago and push the battery all the way back to its tray.

Step 12: Secure the battery by reattaching the retaining bracket, and don't forget to retighten the nuts.

Step 13: Reattach the front panel of the battery tray, clip the wiring loom back in its place and reconnect the wiring plug.

Step 14: Replace the positive lead down to the positive terminal and tighten the nut securely. You can also apply a little amount of petroleum jelly on the positive terminal to avoid corrosion and return the battery cover.

Step 15: Replace the air cleaner housing in its place, then reattach the rubber strap to secure the air intake hose.

Step 16: Attach the pipe to the bracket and reconnect the sensor plug. Refit the hose back to the air outlet and retighten the retaining clamp to secure it in place.

Step 17: Remove the cover on the negative lead and reattach it to the negative terminal by tightening the nut up.

And there you have it! You've just replaced the battery in your Ford Focus.

How long does the battery in a Ford Focus last?

The battery in a Ford Focus lasts around four years, but this can vary depending on different factors like driving habits, weather conditions, the brand of the battery, etc.
