Signs That Indicate It’s Time to Replace Your Car Battery
Before we dive into the signs that indicate it’s time to replace your car battery, it’s essential to understand the importance of the Cold Cranking Amps (CCA) rating. The CCA rating measures a battery’s ability to start an engine in cold temperatures. A higher CCA rating indicates a battery’s ability to provide more power to start the engine.
Here are some common signs that indicate it’s time to replace your car battery:
-
Slow engine crank: If your engine takes longer than usual to start, it may be a sign that your battery is losing its ability to provide enough power.
-
Dim or flickering headlights: A weak battery can cause your headlights to dim or flicker, especially when you’re driving at night.
-
Dead battery: If your battery dies unexpectedly, it may be a sign that it’s reached the end of its lifespan.
-
Age: Most car batteries have a lifespan of around 5-7 years, depending on the type and quality of the battery.
-
Corrosion: Corrosion on the terminals or cables can reduce the battery’s performance and lifespan.
-
Swollen or bloated battery: A swollen or bloated battery is a sign of internal damage and should be replaced immediately.
