The most obvious sign is slow engine cranking, especially on hot days when you’d expect your car to start easily. If your engine turns over slowly or makes clicking sounds, your battery is likely failing. Other warning signs include dim headlights, dashboard warning lights, or electrical components that work intermittently. In Arizona, you might also notice white corrosion around the battery terminals, which happens faster in extreme heat. Don’t wait until you’re completely stranded. If you notice any of these symptoms, especially if your battery is over two years old, it’s time for a replacement. We can test your battery on the spot and let you know exactly how much life it has left.
