8 Dying Car Battery Warning Signs You Shouldn’t Ignore

While batteries can fail without warning, there are some warning signs that your car battery may be nearing the end of its lifespan or require repair. Your car will give you a heads-up that its battery is fading fast.

Ignoring these clues means risking getting stuck in a no-start situation at the worst possible moment. Whether you’re late for work or stuck miles away from home, a dead battery ranks among the most frustrating car troubles.

The smart move? Learn to identify the 8 common red flags that your car battery is on its last legs. With some caution, you can catch the issue early and avoid an untimely battery failure. 

So don’t get caught by surprise! Read on to learn the top indicators of a dying car battery – 

1. Engine is Slow to Start

One of the first signs of a dying car battery is if your engine takes a little longer than normal to start up and get running. When you turn the key, you might hear the starter motor cranking more slowly and struggling to get the engine firing. 

This is a clear sign the battery doesn’t have enough power left to start the engine over quickly and strongly like it used to. Pay attention if your engine seems slow upon startup.

2. “Check Engine” Dashboard Light On

While the “check engine” light can mean any number of things, it’s possibly indicating your battery’s charge is low or it can no longer fully power all of your vehicle’s electronics and sensors. The battery provides fluid to engine components that trigger this light. 

When it’s struggling, the light may come on as a warning that something is being inadequately powered by the battery’s failing charge. Don’t ignore this warning light!\

3. Dim Headlights

Have you noticed your headlights seem dim, even with new bulbs installed? Dimming brightness is a symptom of your battery running out of juice. As batteries discharge, they can no longer fully power lighting systems. 

Your headlights may seem lagging to reach full brightness, or your interior lights may be dim as well. It’s a sign your battery isn’t maintaining a full charge like it should.

4. Corroded Battery Terminals

Corrosion buildup around the positive and negative terminals is a visual indicator that your battery may be having issues. As batteries discharge gases, fluid can leak out and cause deposits to form around the terminals. 

While some small corrosion is normal, excessive buildup means your battery may be overcharging or too old. Corrosion can drain your battery by creating electrical resistance.  

5. Swollen Battery

If you notice your battery casing is swelling up and looks bloated, that’s not a good sign. As batteries age, internal chemistry changes can cause gases to get trapped inside, swelling up the outer casing. Once it starts to swell, it indicates internal issues with your battery and means it’s reaching the end of its life and will need to be replaced soon.

6. Car Electrical Issues

When your battery just can’t hold enough charge, it can cause all kinds of electrical issues. You may notice 

• Radio or dashboard lights flickering
• Accessories acting up
• Issues with starting in cold weather
• Multiple warning lights coming on randomly. 

If the battery charge is too low, it can cause electrical systems to go haywire since they aren’t getting the power they need to operate reliably.

7. Odd Smell From Your Battery

When the battery casing gets damaged or the internal chemistry goes off, you may detect an odd sulfuric or rotten egg-type smell coming from your battery. This indicates a leaking battery that is failing and will need to be replaced very soon. Don’t let this go unaddressed, as leaking battery acid is extremely corrosive.

8. Your Battery Is Old

Of course, one of the simplest indicators for battery replacement is the age of your battery. Car batteries typically last 3-5 years. If yours is hitting the 5-year mark, it’s a wise idea to get it tested and replaced if it’s not holding a full charge anymore. Age alone will precipitate battery degradation over time until it can no longer reliably start your engine.
