Your car battery is one of the most important components of your vehicle. Without it, your engine won’t start, your lights won’t work, and all the electrical systems you rely on will fail. If your battery stops working unexpectedly, you could get stuck on the road at the worst possible time.
To avoid that, it’s important to know when your battery is showing signs. In this article, we’ll explore 7 common signs that indicate it’s time for a car battery replacement—so you can take action before it fails and leaves you stuck on the road.
1. Slow Engine Crank
One of the earliest signs that your car battery needs to be replaced is when your engine starts slowly and takes longer than usual or makes slow sounds when you start your car. It indicates that your car battery is losing power and requires recharging or you have to change your car battery soon.
What to do: If you are near a vehicle repair shop check your current battery condition or if you don’t want to take the hassle of visiting a garage you can rely on Car Fix Pro Dubai if you are located in Dubai City. They can check or even replace your old or dead battery with a new high quality car battery.
2. Engine light stays on
If your engine light stays on after the engine starts, it’s time to get your batteries checked by an experienced mechanic, because it means that it’s already weak or near to dead or there could be other factors causing it. When the battery is weak, it often causes the engine’s electrical components to malfunction.
What To Do: When you see the engine light steady after cranking up your engine, take your car to a professional mechanic or book a mobile car mechanic to look at it.
3. Low Battery Fluid Level
The fluid inside a car battery plays a crucial role in generating the electrical energy needed to power up the vehicle. If the battery fluid level is low, the battery has to work harder than usual to produce power. This extra effort can cause the battery to wear out faster and reduce its overall lifespan.
What To Do: Checking the battery fluid regularly can help you make sure your battery stays healthy and works properly. If you notice the fluid is low, you should refill it.
4. Swollen or Bloated Battery
If your car battery looks swollen or bloated, it means it has been exposed to too much heat or overcharging. This puts extra strain on the battery and makes it wear out faster. A swollen battery can also be dangerous—it might leak acid or, in rare cases, even explode. If you see any swelling or bulging on your battery, it’s important to replace it right away to keep your car safe and working well.
What to Do: If you notice your battery is swollen, don’t try to fix it yourself. Avoid driving your car and have a mobile car mechanic replace the battery on-site as soon as possible. You can choose Car Fix Pro Dubai if you are located in the City.
5. Corrosion
This is a common problem in car batteries. Have you noticed a buildup of a white or greenish powdery substance on your battery terminals? That’s corrosion. If you notice this powdery substance on your battery terminals, do this.
What to Do: To clean corrosion, mix baking soda and water to create a paste, then apply it to the terminals with a toothbrush. Scrub gently until the corrosion is gone. You can also use a specialized battery terminal cleaner for this. If cleaning doesn’t solve the problem or corrosion keeps coming back, it’s time to replace your battery to avoid further issues.
6. Electrical issues
Examples of malfunctions are when your headlights are dimming or flickering, or your radio has poor reception or the clock keeps on resetting, or your power windows are stalling or stopping or making unusual noises.
What to Do: If you see any of these signs, it’s a good idea to get your battery checked and replaced if needed to avoid bigger problems.
7. Age of the Battery
Even if there are no obvious symptoms, car batteries typically last between two to three years under normal conditions. Factors such as extreme weather like Dubai, frequent short trips, and heavy electrical usage can shorten this lifespan.
If you notice any of these signs, it’s best to replace your vehicle battery before it fails completely.
