1. Slow Engine Crank or Hard Start

One of the most common and early signs of a dying battery is a slow or sluggish engine crank.

Symptoms:

• The engine takes longer than usual to start.

• You hear a dragging or clicking noise before the engine turns over.

This happens because the battery lacks enough power to crank the engine efficiently. If your car struggles to start more than once, it’s a sign that your battery may be on its last legs.

2. Dim Headlights and Electrical Issues

Your car battery powers all the electrical components, including:

• Headlights

• Dashboard lights

• Power windows

• Air conditioning

• Stereo systems

If these systems start acting erratic or the lights appear dimmer than usual, it could be due to a weak battery.

What to Watch For:

• Flickering interior or dashboard lights

• Dimming headlights while driving at night

• Sluggish power window operation

These are clear indicators your battery is struggling to supply adequate power.

3. Battery Warning Light on Dashboard

Your car’s dashboard has a battery-shaped warning light, which glows if there’s a problem with the charging system.

Reasons for the Light:

• Faulty alternator

• Poor battery connection

• Low battery voltage

• Corroded terminals

While this doesn’t always mean the battery is the culprit, it definitely warrants a battery check-up.

4. Corroded or Swollen Battery Terminals

Pop open your car’s hood and inspect the battery. If you notice white or blue-green powder on the terminals or cables, it’s a sign of corrosion. Corrosion can disrupt the flow of electricity and cause frequent starting issues.

Additionally, a swollen or bloated battery case indicates overcharging or overheating—a sure sign your battery needs replacement immediately.

5. Battery Age: More Than 3 Years Old

Even if your car starts fine, age alone is a good reason to be cautious.

Most car batteries have a life span of 3 to 5 years. If yours is nearing or has crossed that range, it’s wise to have it tested regularly.

Factors that reduce battery life:

• Extreme heat or cold weather

• Frequent short drives

• Leaving lights or accessories on while parked

✅ At Exide Battery House, we offer free battery health checks to help you assess if your battery is still fit or needs a change.

6. Rotten Egg Smell or Leakage

If you detect a rotten egg-like odor (sulfur smell) from the engine area, it may be due to leaking battery acid. This can be dangerous, not just for your battery but also for other engine components.

Leakage can corrode other parts and is a clear warning sign that the battery is damaged internally.

Act Immediately:

• Stop using the battery

• Do not touch the leakage

• Get professional assistance

7. Car Won’t Start at All

This is the most obvious and final sign—a completely dead battery. If your car doesn’t respond when you turn the key or push the start button, and jump-starting works temporarily, your battery is likely dead or beyond saving.

In such cases, replacement is the only solution.
