Starting: Put the car key in its ignition and turn the first half. What happens next? Your car wakes up and lets you know that you can commence the journey. It happens only because of the battery.

Now, you can start the air vents, power on the interior lights, or listen to music without turning on the engine. All the credit goes to the car battery.

However, if you do any of these for a long time without starting the engine, car’s battery will discharge soon.


Lights: Headlights, rear or front indicators, and any other customized lights take power from the car’s battery. Means, you can see others and be seen even if the car’s engine is turned off. Apart from that, a car’s battery also powers the 12V connector, USB ports, and music player present on your dashboard.

  • You need to repeatedly charge the battery manually.
  • The car is struggling to ignite its engine, especially in the winters.
  • A voltmeter shows a reading of 10.5V or less

Sometimes, it’s the alternator that needs replacement. On an average, alternators last for 60, 000 miles.

However, its life might be as low as 40, 000 or high as 100, 000 miles; depending upon the car’s make and model.

So, if you notice that the battery is not co-operating while the car is moving or its engine is on, then the problem could be with the alternator.
