Signs of a Failing Car Battery
A failing car battery can exhibit a range of symptoms, from minor issues to major problems. Here are some common signs that indicate you need a new car battery:
Slow Engine Crank
One of the most common signs of a failing car battery is a slow engine crank. If your engine takes longer than usual to start, it may be a sign that your battery is losing its charge. This can be caused by a variety of factors, including a weak battery, corroded terminals, or a faulty alternator.
Dim or Flickering Headlights
If your headlights are dim or flickering, it could be a sign that your battery is not providing enough power to your electrical system. This can be caused by a weak battery, loose connections, or a faulty alternator.
Dead Battery
A dead battery is one of the most obvious signs that you need a new car battery. If your battery is completely dead, you may need to jump-start your car or have it towed to a repair shop.
Swollen or Bloated Battery
A swollen or bloated battery is a sign that it’s overheating or experiencing internal damage. This can be caused by a variety of factors, including a faulty alternator, a clogged battery vent, or a manufacturing defect.
Age of the Battery
Most car batteries have a lifespan of around 5-7 years, depending on the type and quality of the battery. If your battery is approaching or has exceeded its recommended lifespan, it may be time to consider replacing it.
