When it comes to your car's battery, one term stands out as critical for performance in harsh weather: Cold Cranking Amps (CCA). This often-overlooked rating is key to ensuring your vehicle starts smoothly, especially during winter's frigid mornings. But what exactly does CCA mean, and how can you choose the right battery for your needs? Let's break it down.

Quick Takeaways

  • What is CCA? A measure of a battery's ability to start your engine in cold temperatures.
  • Who needs high CCA batteries? Drivers in cold climates where temperatures drop below freezing.
  • Where to test your battery? Visit your nearest Batteries Plus for a free battery health check.

What Are Cold Cranking Amps (CCA)?

Cold Cranking Amps measure a battery's ability to start your engine in cold temperatures. Specifically, CCA indicates the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts. The higher the CCA rating, the better the battery performs in cold climates.

For drivers in regions where winter temperatures frequently dip below freezing, a high CCA rating is essential to ensure reliable starts and prevent battery failure.

Understanding Other Battery Ratings

In addition to CCA, there are other important metrics to consider when evaluating car batteries:

  • Reserve Capacity (RC): Measures how long a battery can power essential systems if the alternator fails.
  • Marine Cranking Amps (MCA): Similar to CCA but tested at 32°F, making it relevant for marine batteries.

Factors That Affect Battery Life

Several factors influence how long your car battery lasts:

  • Temperature: Extreme cold reduces a battery's capacity to deliver power.
  • Age: Older batteries lose their ability to hold a charge over time.
  • Usage Patterns: Frequent short trips prevent the alternator from fully charging the battery.
  • And many more.

Learn the signs of a failing battery so you can recognize when it's time to replace your car battery before it's too late.

How to Choose the Right Battery

When selecting a new battery, keep these tips in mind:

  • Check Your Owner's Manual: It will specify the recommended CCA rating for your vehicle.
  • Consider Your Climate: Drivers in colder regions should prioritize higher CCA ratings.
  • Opt for Quality Brands: Premium batteries often come with better warranties and reliability.
