6 Signs That Indicate That Your Automotive Battery Needs Urgent Replacement





When was the last time you had your automotive battery checked? We often focus on our vehicles' exterior, interior, and mileage, but the battery tends to go unnoticed until it fails. Yet, it plays a critical role in keeping our vehicles running smoothly.

Like the heart in our body, the car battery is essential for the vehicle’s overall functioning. If it fails, various systems, including the air conditioner, music system, and phone charger, will stop working, affecting your driving experience.

When the battery's condition deteriorates, the vehicle shows some signs. It is important to pay attention to them and consider an automotive battery replacement if necessary. Before diving into the signs of a failing car battery, let us briefly understand its function to clarify its role and importance.

Why Is a Car Battery Important?

The car battery powers the engine, so if it’s not functioning properly, you won’t be able to start your car. The battery supplies electricity to various systems, such as in-car infotainment, air conditioning, power windows, and others.

Typically located under the hood, these rechargeable batteries recharge while the engine runs. If the battery is not working optimally, you may notice that driving for a few minutes can restore its power even if you manage to start the engine

It is important to regularly check the battery's fluid levels and signs of corrosion to keep it running for a long time.

Primary Reasons for Battery Damage:

  • 1. Wear and tear: Automotive batteries are built to last 2 to 5 years. If maintained well, they may work for one or two more years. After that, you need to consider changing the battery.
  • 2. Corrosion: Battery terminals may accumulate lead sulphate crystals over time. Sulfation on the battery plates significantly reduces the battery’s ability to retain electrical flow. As a result, you may encounter frequent problems when starting the car or with the electrical system.
  • 3. Extreme temperature changes: Harsh weather conditions deteriorate the battery’s performance. This happens when the vehicle is frequently exposed to extreme hot and cold temperatures.
  • 4. Internal issues: In some cases, the battery may fail to perform due to manufacturing defects.
  • 5. Lack of maintenance: It is essential to check the battery's voltage and fluid levels regularly and clean its terminals regularly. The battery may die early if you do not follow these basic protocols.
  • 6. Drains: In the long run, accessories like interior lights or alarms drain the battery. The battery health may deteriorate more quickly if you habitually keep the light or other electric devices on when the engine is not running.
  • 7. Faulty alternator:Any issue with the alternator may impact the battery's capacity to recharge while the engine runs. It may prevent the battery from fully charging, resulting in early drain.

When Should You Get the Battery Checked?

  • 1. Sluggish Crank: Difficulty starting the engine when you turn the key or frequent jump-starts suggests that the battery has lost power and needs immediate attention.
  • 2. Dim lights: Vehicle lights primarily use battery power. So, when you observe that the headlights, interior, and dashboard lights are dim, it is time for automotive battery replacement.
  • 3. Failing electrical components: Electronic components such as power windows, seats, and the infotainment system draw power from the vehicle’s battery. Their deteriorated performance indicates problems with the battery. A failing battery will also impact the functionality of power locks and the radio. If you observe any inconsistency in their functionality, it is most likely due to deteriorated battery performance.
  • 4. Dashboard warning light: A battery or charging warning light flashing on the dashboard indicates potential problems with the vehicle’s battery.
  • 5. Strange smell: If the battery is internally damaged, it will produce an odour similar to a rotten egg. One should not ignore this sign and instantly approach the mechanic for a battery change.
  • 6. Clicking sound: The car’s engine starts only when the starter motor receives sufficient current from the battery. When the battery cannot provide adequate power to start the engine, it makes a strange clicking sound. Any sound during ignition attempts indicates something is wrong with the vehicle’s battery.
