Your car battery is one of the most important components of your vehicle. It powers the starter motor, ignition system, and all the electrical components. But like any battery, it doesn’t last forever. How can you tell when it’s time to replace your car battery? Here are the most common signs:
Signs Your Car Battery Is Failing
- Slow Engine Crank: When you turn the key, the engine turns over slowly or takes longer to start.
- Dim Lights: Headlights and interior lights appear dimmer than usual.
- Warning Lights: The battery or check engine light shows on your dashboard.
- Swollen Battery Case: Heat or age can cause the battery casing to bulge or crack.
- Old Age: Most batteries last 3 to 5 years. If yours is older, it might be time to replace it.
- Electrical Issues: Radios, power windows, and other electronics don’t work properly
Why Early Replacement Matters
Waiting until your battery dies completely can leave you stranded—especially in Auckland’s busy traffic or colder winter mornings. Replacing your battery early saves time, money, and hassle.
