Ford Mondeo Key Battery Type

If you own a Ford Mondeo, then you know that the key battery is an important part of the car. This type of battery is responsible for powering the electronic components in the key, which includes the transmitter that sends signals to the car’s immobilizer. Without a working key battery, your car won’t be able to start.

So what type of battery does your Ford Mondeo use? It turns out that there are two different types that can be used: CR2032 and CR2025. The CR2032 is a 3-volt lithium coin cell battery, while the CR2025 is a 2-volt lithium coin cell battery.

Both of these batteries are commonly found in stores that sell electronics. When it comes to choosing between the two types, it really depends on your personal preference. The CR2032 will provide more power and thus has a longer lifespan, while the CR2025 is cheaper and easier to find.

Ultimately, it’s up to you to decide which one is best for your needs. We hope this information has been helpful! If you have any further questions about replacing your Ford Mondeo’s key battery, feel free to contact us or visit our website for more resources.
