We are all aware of the fact that we need a working battery to start the car, no matter if it’s a traditional gasoline car or electric vehicle. If the battery health is subpar it can significantly cause an unexpected breakdown and result in unwanted repair bills. Batteries are usually more prone to failure when they’re left unused for a longer period or in rather cold weather.
There are several chemical substances that go into making batteries. Chemical changes produce the power needed for a car’s different functionalities. However, over time, the chemical agents naturally lose the effectiveness needed to generate the power for a battery.
The death of batteries in cars is caused by a variety of factors, all of which contribute to a reduction in vehicle fuel economy in one way or another. In this article, our experts at Porsche Workshop Dubai will guide you through on how a bad battery can affect the performance of your vehicle and how to check the health of your battery and avoid a potential breakdown on road.

1. Check Instrument Cluster Gauge
By taking a look at the battery by popping the hood will barely take a minute for visual inspection but the standard procedure usually starts by checking for the indicators. If your car’s battery is not carrying out up to its potential, your vehicle’s diagnostic system will point to the problem on your instrument cluster. All you need to do is to look if your battery indicator is on in the cluster gauge. If it doesn’t show anything like that you can go on and check the battery itself.
Batteries have a built-in indicator gauge as well that changes the color when the battery is not performing well. The color interpretation is printed right on the battery.
2. Spot The Signs of Waning Battery
Many day-to-day things can show that your battery health is fading. If you feel your headlights are dim when at idle but brighten up when you put the rev on. Another factor that indicates a failing battery is a struggling starter motor when you switch the ignition on. Furthermore, a sudden change in sound when you’re idle and turn on an electrical component like AC is another sign that your battery is waning and needs to be replaced.
3. Check The Voltage
If everything works well until now, check the battery’s voltage with the help of a standard multimeter. If the meter shows a reading of fewer than 12.2 volts, then it should be considered too low. Repeat the same process with the running engine. This time you should look for a reading of at least 13.4 volts but the measurement shouldn’t exceed 14.7 volts. Don’t forget to set your multimeter to a DC voltage setting before taking the measurements.
4. Conduct A Load Test
While the multimeter still measures voltage, a load is applied to the engine to force it to work harder. Simply turn on your car and use a multimeter to measure “min/max” voltage. While starting an engine requires a lot of energy from the battery, which puts some strain on it and can cause the battery to go flat. “Success” is determined by maintaining at least 9.6 volts for 15 seconds. Your headlights and radio should be turned on as soon as the engine starts.
5. Conduct Electronic Test
It is recommended to get this test conducted by the specialists like Porsche Workshop in Abu Dhabi to get a better analysis of your battery health. You’ll need a specialized electronic tester for this test. A frequency wave is sent to the inner chemical layers of the battery, and the return signal is analyzed to determine the condition of the cells. An instrument that displays a healthy state result qualifies as a pass.
The electronic tester that you have at your disposal should be able to measure the specific voltage and capacitance ranges that your battery has.
How Dead Battery Affects Car Performance?
This is something people are often seen confused about whether a bad battery will really have a direct impact on their car’s performance or not. But what we need to consider is that it mostly has indirect impact on your car’s performance other than engine which runs on power. It is the parts of your car that are at a potential risk in case of a bad/dying battery.
1. Short Alternator Life
The primary function of a car battery is to start the vehicle’s engine. Once the engine starts, the inverter in the car’s heart takes over the tasks. Processor for a wide range of automotive parts, as well as a regulator of automobile battery levels. Whenever the battery voltage drops below 12V, the ac power is put under a lot of strain. The alternator’s longevity is often shortened given the ongoing load placed on it. It also affects the car’s battery structural performance over time.
2. Fuel Consumption
It’s not just the inverter that’s suffering. It makes the car engine work harder than usual. Also, on short rides, such extra imposing leads to excessively relatively high fuel consumption. All of this contributes to a decrease in car’s fuel economy over time.
3. Ineffective Accessories
Often, car accessories that are powered by a sluggish car battery will suffer. Such operation has a negative impact on the everyday runs. Even accessories which are only powered intermittently by the car’s battery can suffer from this. A few of the more common ones are computing systems, power windows, heaters, dashboard and the seats.
4. Poor Processing
There’s still a lot of strain on a poor car battery. There are times when an automobile’s computer struggles to keep up with the demands placed on it. There are a number of factors that affect the accuracy of the instrument cluster, such as mechanical thrust and electronic power stress.
For example, a failing automobile’s battery makes it difficult for the vehicle to predict the amount of fuel consumption in compared to the total of combustion it produces. Bad batteries have a negative impact on devices like sensors because of the low voltage. While driving a car, a computer can no longer shut off the gas tanks. Consequently, the vehicle’s exhaust produces a large amount of smoke.
In addition to affecting the start of the engine, a dead battery can also cause problems with the alternator, which is responsible for charging the battery and providing electrical power to the car while it is running. If the alternator cannot charge the battery, the battery may become fully depleted and unable to start the engine. This can lead to additional damage to the alternator and other electrical components, potentially requiring expensive repairs.
Moreover, a dead battery can also impact the performance of the car’s onboard computer systems. Modern vehicles are equipped with sophisticated electronic systems that rely on a stable power source to function properly. If the battery cannot provide a steady power source, these systems may malfunction, causing a range of issues, such as poor fuel efficiency, reduced engine performance, and warning lights appearing on the dashboard.
Conclusion
In conclusion, a dead battery can have a major impact on the performance of a car, from the inability to start the engine to affect the operation of various electrical systems. Regular maintenance and battery checks can help prevent the inconvenience and costs associated with a dead battery.
