You’re stranded on the highway, jumper cables hooked up, and a kind stranger trying to help—but no matter how many times you try, your car won’t start. Even after waiting 10–20 minutes with the cables connected, nothing happens. Now what?
This frustrating situation usually comes down to two possible culprits: either your battery is completely dead and needs replacing, or your alternator has failed and is no longer charging the battery.
If your car won’t start, your best bet is to call a tow truck or get a ride to the nearest auto shop for assistance, such as KC Automotive. But next time, you can avoid this headache by knowing the warning signs before your battery or alternator gives out. In this blog, we’ll cover key symptoms to watch for so you can replace or maintain these crucial parts before they leave you stranded.
Signs to Look Out For?
Your car battery powers everything electrical in your vehicle, from the headlights to the phone charging port. Meanwhile, the alternator is responsible for recharging the battery while the engine is running. It generates energy through the movement of gears, ensuring your battery stays charged.
With that in mind, here are key warning signs that your car battery or alternator may be failing.
Bad Battery Symptoms:
- The check battery light is on
- Sulfur or rotten egg odor – Means your battery is leaking
- Slow cranking when trying to start your car
- Clicking sound when you try to start your car
Bad Alternator Symptoms:
- The check battery light is on
- Repeated dead batteries
- Headlights are too dim or overly bright
- Malfunctioning electric powered accessories
When Should You Replace Your Alternator or Battery?
Car Battery:
Most car batteries last between 3–5 years, but factors like climate and driving habits can shorten their lifespan. If your battery is over three years old or you notice warning signs of failure, it’s best to replace it before it leaves you stranded.
Alternator:
A well-functioning alternator typically lasts 7–10 years or between 80,000–150,000 miles. However, if you experience any signs of alternator failure, don’t wait. Replacing it at the right time can prevent unexpected breakdowns and costly repairs, so you won’t be stranded on the highway with a dead car ever again!
