In this article, we will guide you through the process of replacing a car battery in a Ford Focus Electric.

1. Understanding the Ford Focus Electric Battery:

The Ford Focus Electric is equipped with a high-voltage lithium-ion battery pack to power its electric motor. It is essential to understand the type of battery and its location before attempting to replace it. Here are some key details about the Ford Focus Electric battery:

The Battery Type

The Ford Focus Electric utilizes a lithium-ion battery pack, which is the most common type of battery used in electric vehicles. It offers high energy density, longer lifespan, and efficient power delivery.

Battery Location

The battery in a Ford Focus Electric is usually located beneath the vehicle’s floor, between the front and rear wheels. This placement helps to distribute the weight evenly and maintain a low center of gravity for better stability.

Battery Capacity

The battery capacity of a Ford Focus Electric can vary depending on the model year. Older models may have a battery capacity of around 23 kWh, while newer models can have up to 33.5 kWh.

2. Tools and Materials Required

Before you start replacing the car battery in your Ford Focus Electric, gather the necessary tools and materials to ensure a smooth process. Here is a list of items you will need:


  • Socket wrench set
  • Torque wrench
  • Adjustable wrench
  • Insulated gloves
  • Insulated screwdriver


  • New car battery specific to your Ford Focus Electric model
  • Terminal cleaning solution
  • Battery terminal protector spray
  • Battery cleaning brush
  • Clean cloth or rag

3. Precautions and Safety Measures

Working with a car battery requires caution as it involves high-voltage components. Here are a few precautions to ensure your safety:

1. Turn Off the Car

Before replacing the battery, turn off the vehicle and make sure all electrical systems are switched off. This step will prevent any accidental electrocution or damage to the vehicle’s electrical components.

2. Wear Protective Gear

Put on insulated gloves and safety glasses to protect yourself from any potential electrical shocks or acid spills from the battery.

3. Disconnect the Negative Terminal First

When disconnecting the old battery, always remove the negative terminal first. This reduces the risk of short circuits or electrical damage.

4. Handle the Battery with Care

Lithium-ion batteries are sensitive to extreme temperatures and physical damage. Handle the battery gently and avoid dropping or hitting it against any hard surfaces.

5. Follow Manufacturer Guidelines

Always refer to the vehicle’s owner manual or the battery manufacturer’s guidelines for specific instructions related to your Ford Focus Electric model.

4. Step-by-Step Guide to Replacing the Car Battery

Now that you are familiar with the Ford Focus Electric battery and the necessary precautions, let’s dive into the step-by-step process of replacing the car battery:

1. Park the Vehicle in a Safe Area

Find a well-ventilated and flat surface to park your Ford Focus Electric. Engage the parking brake and ensure the vehicle is in “Park” mode.

2. Disconnect the Negative Terminal

Using an adjustable wrench or a socket wrench, loosen the bolt securing the negative terminal (-) of the old battery. Once loosened, carefully remove the cable and set it aside, ensuring it doesn’t come into contact with any metal surfaces.

3. Disconnect the Positive Terminal

Next, disconnect the positive terminal (+) in the same manner as the negative terminal. This step ensures no electrical current is flowing when removing the battery.

4. Remove the Battery Hold-Down Clamp

Inspect the battery hold-down clamp securing the battery in place. Depending on the model year of your Ford Focus Electric, the clamp may have bolts or screws. Use the appropriate tool to remove the clamp and set it aside.

5. Detach Battery Vent Tube (If Applicable)

Some Ford Focus Electric models may have a vent tube connected to the battery. If present, carefully detach the vent tube from the battery.

6. Remove the Old Battery

Gently lift the old battery out of its compartment and place it in a safe location away from children, pets, and direct sunlight.

7. Clean the Battery Compartment

Thoroughly clean the battery compartment using a battery cleaning brush and a mixture of baking soda and water. This solution will neutralize any acidic residue and prevent corrosion.

8. Install the New Battery

Place the new battery into the compartment, ensuring it is properly aligned. Reattach the battery hold-down clamp and tighten the bolts or screws to secure the battery in place.

9. Reconnect the Positive Terminal

Connect the positive terminal (+) to the new battery and tighten the bolt securely. Avoid over-tightening, as it may damage the battery terminal.

10. Reconnect the Negative Terminal

Finally, reconnect the negative terminal (-) to the new battery and tighten the bolt. Ensure all connections are secure and free from any dirt or corrosion.

5. Testing and Maintenance:

After replacing the car battery in your Ford Focus Electric, perform a few tests and follow some maintenance practices to ensure optimal performance:

1. Turn on the Vehicle

Start the car and check if all electrical systems are functioning correctly. Test the headlights, interior lights, power windows, and any other electrical components.

2. Perform a Battery Health Check

If your Ford Focus Electric has a battery health monitoring system, monitor the battery’s state of charge regularly. This will help you keep track of the battery’s condition and plan for future replacements if needed.

3. Clean the Battery Terminals

Regularly clean the battery terminals using a battery cleaning brush and a mixture of baking soda and water. This practice helps prevent corrosion and ensures good electrical contact.

4. Follow the Manufacturer’s Maintenance Schedule

Refer to the vehicle’s owner manual for the manufacturer’s recommended maintenance schedule. Adhering to these guidelines will help prolong the life of your car battery and maintain its performance.
