A dead battery always seems to happen at the worst possible time. Whether you’re rushing to work or heading out for a road trip, a failing battery can leave you stuck. The good news? Your battery gives you warning signs before it dies. Ignoring them could mean expensive repairs and unexpected breakdowns.

Here are seven key signs that your car battery needs replacing—and what you can do to avoid disaster.

1. Slow Engine Crank

If your car takes longer than usual to start, your battery may be weakening. A healthy battery provides a strong charge to the starter motor. A failing one struggles, causing a slow cranking engine or a clicking noise when you turn the key.

2. Dim or Flickering Lights

Your headlights, dashboard, or interior lights should be bright and steady. If they flicker, dim when idling, or brighten only when you accelerate, your battery is losing power. A weak battery can also affect your radio, power windows, and aircon.

3. Electrical Malfunctions

Modern cars rely heavily on electrical systems. If your power windows move sluggishly, your door locks hesitate, or your infotainment system malfunctions, your battery might be struggling to provide enough power.

4. Rotten Egg Smell

A strong sulfuric smell under the hood usually means your battery is leaking. This can lead to corrosion, electrical issues, and even damage to nearby components. If you notice this, replace your battery immediately.

5. Corrosion on Battery Terminals

Check your battery terminals regularly. If you see white, powdery buildup around them, it could be causing a weak connection. While light corrosion can be cleaned, heavy corrosion signals an aging battery that needs replacing.

6. Swollen or Bulging Battery Case

A healthy battery is flat and rectangular. If your battery appears swollen, warped, or cracked, it has been damaged by excessive heat or overcharging. A bulging battery is a serious safety risk and should be replaced immediately.

7. Warning Lights on Your Dashboard

If your battery warning light or check engine light is illuminated, don’t ignore it. It could mean your battery isn’t holding a charge or that your car’s electrical system is under strain. Have your battery tested before it fails completely.
