How to tell if a car battery is dead

Normally, a car battery takes a long time to die, but there are some warning signs to look out for to determine if this has occurred. You can read about them below:

Starter motor cranks

A strong indicator to take into consideration is if the starter motor slowly cranks and stops suddenly when attempting to turn the ignition key. This means that the battery has stopped functioning.

Electronic components won’t work

Another factor worth paying attention to is if the lights, cell phone charger, dashboard computer, heated seats, or radio stop operating while the key is in the ignition. That’s because a battery provides power to electronics in the car. Once a battery loses its charge, then it can’t power the electronics. 


Another sign of a dead battery is corrosion. A quick way to check for corrosion is if there’s a white substance on the battery. This causes voltage problems, making the car inoperable.

Check engine light

If the check engine light is on, then it could mean that the battery’s juice has been depleted. Checking the car manual can help determine whether or not it’s a battery-related issue.

Old battery

If your battery is 4-6 years old, then it likely died due to old age. The battery’s life is affected by climate, how it’s used, and electronic demand.

Rotten smell

A car battery shouldn’t have any bad smells to it. If there is a rotten egg-like odor, then it means the battery is leaking gas, which can damage other parts of the engine.

How to jump-start a car

A dead car battery is a huge burden to anyone traveling on the road. The good news is that you can use one of these power banks presented in this article to start it right back up. In order to do that, first, you need to turn off the ignition and set the parking brake. Put the automatic transmission in park and standard transmission in neutral. Find the battery, keep the red and black cables from getting in contact with each other. Identify the battery’s positive and negative terminal and ensure they’re clean. Verify the power bank and car are off before connecting the cables.

To start things off, you will need to connect the red clip of the positive cable to the dead battery’s positive terminal. It will have “POS” or “+” on it. Then, connect the black clip to an unpainted metal part of the engine part, which shouldn’t be near the battery. After the cable clamps are hooked up, turn the power bank on and start your vehicle. If your car starts successfully, then turn the power bank off and remove the cable clamps in reverse. This is done by removing the negative clamps first, then the positive clamps. You should ensure the clamps do not come in contact with each other. Put the power bank away. Finally, let the car battery recharge by driving it around for 20 minutes. 

If your car doesn’t start immediately, you will need to wait 2-3 minutes before starting it again. If it still fails to start, the car battery is likely dead and needs a replacement.
