5 Signs Your Audi's Battery Is About To Give Out

From headlights to spark plugs; the share of electrical components in modern cars has increased in recent times compared to traditional mechanical parts. The component that keeps powering up all these parts is the battery. If it gives up due to old age or any other reason, any part with any kind of dependence on electricity will stop operating.

Knowing when your Audi battery has reached its maximum useful life and when it is about to die can save you from all kinds of electrical problems. The discussion below will help you recognize early symptoms of battery trouble in your Audi.

Recognizable Signs of Battery Failure in a Car

#1- Flashing battery light

The most prominent sign of battery trouble in modern cars is the illumination of the battery light. Your Audi's onboard computer runs diagnostic checks on various parts of the car, including parts associated with electrical charging and storage systems such as the alternator and battery. If the computer senses that there is something wrong with the battery or any part of the charging system, it will immediately activate the battery light to warn the driver.

#2- Trouble starting the engine

Have you been struggling to start your car engine early in the morning? One explanation as to why that might be happening is because of a dying or weak battery. A weak battery will not be able to provide sufficient electrical charge to the ignition system and starter motor, as a result, no matter how hard you try, the engine will refuse to start. Technical glitches in the starter motor, worn-out spark plugs, defective fuel injectors, and a clogged air filter are among the parts that can contribute to battery issues in a vehicle.

#3- Car lights appearing dim

Be it headlights or instrument cluster lights, every light in your car depends on the battery for a constant supply of power. As the battery weakens and its charge storage capacity decreases, your car's lights will start to appear dim. And, yes… they may also start flickering. As soon as you notice that your Audi lights are losing their brightness and flickering as if they are about to explode, then you should reach out to the service center to get the battery tested.

#4- Bloated battery case

If your Audi battery case appears to be bloated, then it is time you visit the nearest Audi service center to find out what is going on with your battery. There are many different things that can contribute to battery case swelling in a vehicle. If for some reason the voltage regulator of the charging system gets damaged, the battery will swell because of overcharging. Old age is another thing that can result in distortion of the shape of the battery case.

#5- Electrolyte leak

Has your car battery been leaking electrolyte for some time now? Such leaks usually indicate that the battery is being overcharged for some unknown reason. You must get to the bottom of the issue and find out the factor that’s been causing the battery to leak out electrolyte.

What Should You Do When You Discover That Your Audi Battery Is At Fault?

Replace it…

Yup, you read that right!!! Being the part that stores electricity to be used by the different electrical appliances of the vehicle, the battery needs special care. There are a few things that you can do to prolong the lifespan of your car battery. Such as;

1. Make sure that the parts of the charging system like the alternator, voltage regulator, etc. are in good condition. If you find out that there is something amiss with any of the above-said parts, don't hesitate to give your mechanic a call.
2. Make sure that there is no parasitic power drain in your vehicle. If your battery is draining overnight, test each wire and relay individually to find and fix the culprit. The thing about parasitic power draw is that it significantly reduces the life span of a car battery.

In Conclusion…

The battery is at the core of your Audi’s electric system. It ensures that no electrical device in your vehicle is deprived of electrical power.
