10 Tell-Tale Signs of a Dead Car Battery

The battery is the lifeblood of your car. It is not only vital for starting your car’s engine but also important in powering all the electrical components of your ride. Without a fully functioning battery, you will not be able to go anywhere with your car. Besides that, getting stranded with a faulty or worse, a dead battery is very inconvenient and can even be dangerous. Luckily, they usually give us a few tell-tale signs that they are about to fail so we can get a replacement battery promptly. Watch out for these ten signs of a dead battery so you can prevent getting caught out in the middle of nowhere. 

Car Doesn’t Start

If your vehicle doesn’t respond at ignition, it might be because the starter motor is not getting power, and your battery is dead. 

Starter Motor Cranks But The Engine Doesn’t Start

When your starter motor activates slowly, but the engine doesn’t turn over, this might also be a sign of a dead battery or sometimes a faulty starter. 

Sluggish Response at Ignition

Having cold weather can affect the battery’s performance, so sometimes, it is quite normal for your engine to be sluggish at ignition. However, if there is no temperature drop in your area and your engine is still slow before turning over, it might be caused by a faulty battery, bad alternator, or starter problems. 

Engine Cranks But Dies Instantly

Suppose your car starts, but then the engine instantly dies. When this happens, it means that your car’s battery charge may just be sufficient for cranking the engine and then fails. Due to this, the signals sent to the engine control module (ECM) will be disrupted, causing the engine to immediately die after turning over. 

Absence of Dome Lights or Door Chime

Once your vehicle’s battery is failing, it will not be able to power your car’s electrical components – including your door chime and dome lights. So if you notice that your vehicle’s door lights are not turning on or you do not hear a chime when you insert your key into the ignition, this might be a sign that your battery is failing. 

Dim Headlights or No Headlights

If you notice that your car’s headlight seems dim and weaker than before or worse, your headlights are not switching on at all, it means you have a weak battery, or your battery is dead. Change your battery when this happens because a reduced light can pose safety issues. 

Check Engine Light Is On

A car’s dashboard has various warning lights to inform you about a specific problem in your car. When you see that the Check Engine light is on, there might be an issue with the electrical system. It might be triggered by various factors such as a faulty alternator, a problem in the wiring system, or a dead battery. 

Battery’s Case is Deformed

Your car’s battery might die when exposed to extreme temperatures or when the alternator is overcharging. When your battery is swollen or bloated, you have to replace it immediately. 

Weird Smell

If you detect an odd smell in your car, it might be caused by battery acid that is leaking. Once you smell rotten eggs when you open the hood, have your car checked and replace your battery. 

Corroded Battery Terminals

If you see a blue-green, ashy substance on your battery terminals, you may be having a corrosion problem. This may lead to shorter battery life. Besides that, it lessens the battery’s ability to receive a charge, so you may encounter a sluggish response when you start your car. 

What to Do With a Dead Car Battery?

To solve your problem, jumpstarting your dead car battery might be the best solution we can recommend. However, if you do not have a portable jump starter, you can ask another running car to act as donor and jumper cables to execute it. To guarantee a successful result, just note the following steps. 

  • Get your jumper cables. 
  • Position the cars and let them face each other. Note that you should not let them touch and just keep them about 18 inches apart. 
  • Connect the jumper cables correctly. 
  • Start the vehicle. 
  • Detach the jumper cables. 
  • Keep the engine on and drive the car for about 15 to 20 minutes.
