5 Unmistakable Signs Your Mini Cooper Battery Is Failing

Mini Cooper is one of the most popular subcompact cars. It is known for its size and eye-catching exterior design. Its base model is equipped with a turbocharged 3-cylinder 134-horsepower engine and a standard 6-speed manual transmission. An easy-to-use infotainment system and integration of advanced electrical appliances make it one of a kind. Those advanced components need a continuous supply of electric current to stay operational.

The sole purpose of a battery is to power the ignition system, starter motor, and other electrical appliances used in your vehicle. A dead battery jeopardizes the entire electrical system which could shut down your car in the middle of nowhere. So, symptoms of battery failure in your Mini Cooper should never be neglected.

Let us discuss some of the most common causes and signs of battery failure in a Mini Cooper.

What causes a car battery to die?

Extreme environmental temperature, parasitic drainage, and corroded terminals are some of the most common reasons behind battery failure in your Mini Cooper. Moreover, lack of maintenance and aging could also kill the battery of a vehicle. So, keep the battery terminals clean. Besides, if the battery is more than three years old, then replace it immediately. Cover the battery with a suitable insulator to protect it against extreme temperature.

Now, here is a list of some of the common signs of battery failure in your Mini Cooper.

What are the signs of a bad battery?

Flickering headlights

The dim headlight is a sure sign of battery failure in your Mini Cooper. You will notice a random fluctuation in the brightness of the headlights as well as the interior lighting system. Disruption in the electric power supply due to a weak battery is solely responsible for such anomalies. Moreover, other electrical appliances like radio and dashboard will not work as usual.

The engine won’t start

As we discussed earlier, the battery powers the starter and ignition system of your Mini Cooper. The coil packs rely on the battery to get the electrical energy required to fire the spark plugs. The starter motor also depends on the battery power to crank the engine of your vehicle. However, a weak or faulty battery fails to fulfill the energy requirement of these components as a result of which you might not be able to start the engine of your Mini Cooper.

Engine performance issue

Poor engine performance is also a symptom of a weak battery. The engine control module or ECM regulates the engine operation in a vehicle. It analyzes the data it has received from various sensors and makes sure that the engine of your Mini Cooper is operating smoothly. It adjusts the air-fuel ratio within the combustion chamber and also modulates the timing of spark generation by the ignition system. It needs a continuous supply of electric energy to do its job properly. Disruption in the electric current supply to the ECM due to a faulty battery could adversely affect the engine operation.

Check engine light comes on

Illumination of the check engine light is very common in case of a bad car battery. Disruption in the electric current supply could adversely affect the engine operation in your Mini Cooper. When the computer finds out about these abnormalities, it would turn on the check engine light to warn the driver in advance.

Strange odor

If you smell rotten egg or sulfur-like odor while trying to start your Mini Cooper, then it is a sign of a defective battery. A leaking battery is solely responsible for the emergence of such sulfur-like odor. Replace it as soon as possible.

What to do?

A weak or faulty battery could bring your Mini Cooper to a halt in the middle of nowhere. So, if you are noticing one of the above-mentioned signs, then something is clearly wrong with the battery of your vehicle that needs immediate attention. Consult with a car mechanic immediately and replace it as soon as possible.

Conclusion

The sole purpose of a car battery is to store and distribute electric energy. Fault in such a vital component could disrupt the electric power in your Mini Cooper. So, symptoms that indicate the battery of your Mini Cooper is dying should never be neglected.
