A rotten egg smell in car is one of the signs of a dying car battery. Unfortunately, a majority of the auto owners in the industry today don’t know this, so they tend to ignore this foul smell and continue with their journey. Others might decide to clean their cars, hoping that this problem will be washed out. In addition to the rotten egg smell, it’s essential to highlight other signs of a damaged car battery.

1. Dim Headlights

Headlights constitute one of the significant components that use up a car’s battery power. As such, when they start to dim, it indicates that the battery is no longer as powerful as it used to be and needs to be changed. However, you need to check other issues affecting the headlights’ power, such as a faulty alternator, before you buy a new battery.

2. Slow Engine Crank

A slow engine crank is another sign that your car battery is nearing the end of its life. This happens because the battery can no longer provide enough power to start the car engine the way it used to. In most cases, you’ll notice that the machine takes longer than usual to start. If this is the case, it’s advisable to take your car to a reputable auto shop for further inspection and replacement if need be.

3. Check Engine Light Is On

The check engine light is another significant sign that your car battery will die. This warning light usually comes on when the battery voltage is lower than normal. If you happen to see this light, taking your car for a checkup as soon as possible is essential to avoid being stranded in the middle of nowhere. However, a faulty battery connection can also trigger this warning, and that’s why you need a professional to check it out.

4. Sputtering Engine

Another sign of a dying battery is a sputtering engine. This usually happens when you try to start your car, but the engine fails to turn on immediately. In most cases, you’ll hear a clicking sound before the engine finally starts. However, if the battery is completely dead, the engine won’t start at all, no matter how many times you try.

5. Corrosion on the Connectors

Your battery connectors should be clean for the current to flow properly. However, over time, these connectors might get corroded, and this can cause starting issues. In some cases, you might see a white powdery substance on the connectors. This is an indication of corrosion. If you notice this problem, it’s advisable to take your car to a professional for cleaning or replacement.


These are some of the essential signs that your car battery is about to die. These issues, if not attended to in good time, might cause significant problems that might even render your car immobile. As such, it’s advisable to take your vehicle for regular checkups to ensure that all the components are in good working condition. Contact Texford Battery Co for more information.
