Ford Mondeo Battery Problems

Ford Mondeo Common Battery Problems: Top 4 Fixes

Next to the Ford Cortina, very few cars can stand up and claim to be the flagship of their brand. The Ford Mondeo has taken up the reigns and there are very few general problems to consider. Unfortunately, the battery of a vehicle is dependent on various factors and could often lead to frustrating battery issues.

One of the most common issues is that the battery slowly drains when the vehicle is parked. Granted, this does not happen to newer vehicles, but some of the older models might suffer from this. Bear in mind that if the battery light came on, it could be the alternator. However, a car that doesn’t want to start is often a dead battery that needs inspecting.

Battery problems can cause a host of other problems, but the most common would be leaving you stranded and in need of a jumpstart to get going. You must address possible battery faults as soon as possible to ensure safety and a smooth driving experience. We will look at a few of the most common Ford Mondeo Battery Problems.

Many might argue that singling out a vehicle or model type in terms of battery issues is not fair. You might be right, and many battery-related issues could apply to any vehicle. However, you must understand these issues and know how to diagnose them in your Ford Mondeo to ensure you can fix them and be on the road again.

1.      Bad Battery

Problem: One of the most common issues that some of the older model Ford Mondeos had to deal with is a bad battery. The issue often arises when you start the car, and the battery is dead. You won’t have a battery light, which means all the electronics in the vehicle are dead and do not want to function correctly.

Solution: The only solution is to have the battery replaced. Fortunately, car batteries are inexpensive, and it should not take you that long to have the battery fully replaced. You can do this at home, with your basic tools. We recommend visiting a battery store to make sure you are buying the right battery to be replaced.

2.      Corroded Battery Cables

Problem: Battery cables are an essential part of your battery. They connect the components in the engine to the power in the battery. Additionally, they are responsible for charging the battery whilst you are driving. Any rust or corrosion could reduce the quality of contact with the battery and will affect your car.

Solution: You should open these cables and disconnect them from the battery first. Once you have done this, it should be easier for you to see any corrosion. There are plenty of high-quality cleaning products that can be used with a brush to remove the corrosion. We would recommend doing this at home to save a few bucks.

3.      Alternator

Problem: One of the bigger issues affecting your battery is the alternator. The alternator is responsible for charging the battery and making sure that it has enough power when you turn the vehicle off. Alternator issues can be detected if you happen to have battery problems while driving.

The alternator issue can also be detected when you leave the car running for a set time, and still, notice that the battery is draining. The battery is draining much faster than the alternator can charge it back up. This issue could be frustrating and leave you stranded if you do not take care of fixing the problem.

Solution: As for the solution, you can visit most parts stores and ask them to test the alternator. Generally, most stores would not charge you for testing, but they might try selling you a new alternator. If you have someone you can trust, it will be a bonus. However, you should consider getting a second opinion before buying a new alternator.

4.      Blown Spark Plugs

Problem: While this can be considered not part of the battery, the symptoms are often very similar to a dead battery, and you will find that having a dead battery will have the same issue when starting. The vehicle will hesitate when you turn the key and stop dead without even starting, even when pressing the gas pedal.

Solution: Dealing with blown spark plugs is easy, and you will have to replace them. We recommend that when you have troubles with your vehicle starting, you should consider looking at the spark plugs as well. You might notice that the fault is not even related to the battery, and replacing spark plugs is easy and cheap.


How Long Does A Ford Mondeo Battery Last?

The Ford Mondeo Battery is similar to any other vehicle you might drive. The battery needs to be kept in optimal condition, and the car should drive often. By keeping the battery charged and driving a few daily miles, you could extend the life. The average life expectancy of the Ford Mondeo Battery is between 4 and 7-years.

What Is Draining My Car Battery When It Is Parked?

If you have ever stopped your vehicle and found that the battery is dead upon arrival, the cause might be the alternator. However, leaving lights on indoors or not turning off your headlights, could drain the battery. Bad relays can be another cause, but you should start by making sure all the lights are turned off.

What Causes Parasitic Drain On Your Battery?

If you have noticed your battery draining abnormally, you might be dealing with parasitic draining. The issue could rapidly deplete your battery, and you should diagnose the issue. Having electronic faults that constantly need power like damaged lights could be one of the causes. It is vital to make sure all the components are functional.
