How to test a car battery without a multimeter?
If you don't have a multimeter, no problem. We offer car owners a helpful way to test their car battery without performing a test:
Step 1 – Check battery voltage
Start by physically inspecting the car battery. Check for swelling or leakage. Your battery is a front-facing box. Along the way, it's possible the battery terminals are corroded; you should inspect the device for corrosion. If all goes well, continue.

Step 2: Turn on your headlights
You can check the battery by turning on the headlights first without starting the engine. Leave the battery light on for about 10 to 15 minutes.
Step 3: Short start the engine
While the light is still on, start the engine; when the car starts, you will notice the bulb dimming. If the headlights are off or too dim when the machine takes a while to turn over, there may be a problem with your car's battery.

Engine starts slowly
A slow engine revs when starting usually indicates a drained battery. If something goes wrong, the battery won't fully charge, which manifests itself as a slow engine start because the battery can't provide enough power to the starter motor to drive the engine.
If you encounter this problem frequently, it may be because your car battery is low on power.

turn off the light
As mentioned before, a slight dimming of the light is another sign of battery problems. This also applies to problems with interior lights or other electrical components such as windows, electricity, or radios. These types of electrical components are more likely to fail, and the lights will begin to dim before turning off.

click noise
You will hear a crackling sound when the battery is not providing enough power to the engine to start the car. It proves that your battery is dead and your car cannot start.
Battery indicator
When the battery starts working, you will see its indicator light on the control panel. While some models display a picture of the battery, others have a generic check engine light.

If the light on the dashboard lights up or other abnormalities occur, it means that the battery is faulty and needs to be replaced with a new one.
How to tell if the car battery is faulty?
Identify a damaged car battery by its signs. A lot depends on how you feel when using the car. If you pay attention, you can detect a weak or damaged car battery by looking at the following signs:
Looking at the color of the magic eye is the quickest way to identify a damaged car battery. Magic Eyes are usually designed with high-end batteries; if the battery is not green (good), it means you have a problem.
It is detected by a battery status warning light displayed on the vehicle's display. This is also a sign that the battery needs urgent inspection.
