How to Know If Your Car Battery Is Dying (And What to Do)
Is your car struggling to start? Learn the 5 key signs of a dying battery, how to fix it, and when it’s time to replace it. Stay safe and powered with Afchargetech!
Your car battery is like the heart of your vehicle — without it, everything else stops. Whether you drive a sedan, SUV, truck, or generator-powered system, your battery must stay in good health to keep you goig. Unfortunately, most people don’t realize their battery is dying until their car refuses to start.
At Afchargetech, we specialize in diagnosing, installing, and replacing car and power batteries across Nigeria. If you’ve been asking, “Why won’t my car start?” or “How do I know if my battery is dead?”—this guide is for you.
In this comprehensive post, we’ll explain the top 5 signs of a dying battery, what you should do about it, and how to avoid sudden breakdowns. Let’s help you stay safe, powered, and on the move.
1. Slow Engine Crank
Have you noticed your car taking longer than usual to start? That long, dragging “rrr-rrr” sound when you turn the key is a classic red flag. This delay is often caused by a weakened battery struggling to provide enough power to the starter motor.
This sign usually appears before total battery failure and should not be ignored. If it happens repeatedly over a few days, you’re likely dealing with a battery nearing the end of its lifespan.
Afchargetech Tip: Get a free battery check-up at our service center or call us for a home visit. We’ll test your battery voltage and cranking power.
2. Flickering or Dim Dashboard Lights
Your dashboard lights and in-car electronics (like the stereo, GPS, or AC screen) rely on consistent battery voltage. If your dashboard dims or flickers while starting the engine, it’s a strong sign that your battery isn’t producing enough energy.
Low voltage can affect your car’s electrical system and eventually cause sensors or alarms to malfunction.
Afchargetech Tip: Turn off high-drain accessories (headlights, AC, radio) before starting the engine. If the issue persists, it’s time for a test or replacement.
3. Clicking Sound When You Start the Car
If you hear a click-click-click sound instead of the engine turning over, your battery may not have enough power to engage the starter motor. This often happens when the battery is nearly dead.
In some cases, the issue could be dirty terminals, corrosion buildup, or loose connections—especially in Nigeria’s humid and dusty climate.
Afchargetech Tip: Clean your battery terminals regularly and always use anti-corrosion grease after installation.
We also …offer on-site cleaning and tightening services, so you don’t have to get your hands dirty or risk damaging your battery.
If cleaning doesn’t solve the problem, it’s time for a proper battery test or a jumpstart. Remember, continuous clicking without action means your battery is not holding charge effectively.
4. Rotten Egg Smell or Swollen Battery Case
Ever popped your hood and caught a whiff of something like rotten eggs? That’s sulfur — and it’s a tell-tale sign that your battery is leaking acid. This often happens when the battery has been overcharged, overheated, or damaged.
A swollen, bloated, or cracked battery case is also a serious concern. It means gas is building up inside and the internal plates may be damaged. Left unchecked, this can result in leaking fluid, corrosion, or even a hazardous explosion.
Afchargetech Tip: Never ignore a smelly or swollen battery. Turn off your engine immediately and get professional help. We can safely remove and replace damaged batteries and properly recycle the old one.
5. Your Battery is Over 3 Years Old
Most car batteries last between 3–5 years depending on climate, usage, and maintenance. If your battery is older than 3 years, you should begin regular testing every 6 months.
In Nigeria’s hot climate, battery lifespan is often shorter. Heat causes the fluid inside to evaporate faster, weakening the internal structure.
Afchargetech Tip: Check the date code on your battery sticker. If it’s over 36 months old, don’t wait until you’re stranded. Book a free battery health check with us.
What to Do If Your Battery Is Dying
If you’re seeing one or more of these warning signs, here’s what to do:
Clean the Terminals: Use a battery brush and cleaning solution to remove corrosion. Always wear gloves and eye protection.
Try a Jumpstart: Connect jumper cables to another car or use a portable jumpstarter. Make sure to follow the correct order of connection to avoid sparks or damage.
Get a Free Battery Test: At Afchargetech, we use digital testers to assess your battery’s cold cranking amps and voltage.
Replace if Needed: If the battery fails the test, it’s time for a new one. Don’t take chances—especially during the rainy season or holiday travels.
We sell original batteries from trusted brands, offer home delivery, and provide free installation within select locations.
