Frequently Asked Questions
What does CCA mean and why is it important?
CCA stands for Cold Cranking Amps, which measures a battery’s ability to start an engine in cold temperatures. A higher CCA rating means more starting power in cold weather. For most cars, a CCA between 500 and 700 is sufficient, but larger engines or extreme cold may require 800 or more.
How long should a car battery last?
On average, a car battery lasts 3 to 5 years. AGM batteries often last longer, up to 6-7 years, while flooded batteries may need replacement sooner. Factors like climate, driving habits, and vehicle electrical demands affect lifespan.
Can I replace a flooded battery with an AGM battery?
Yes, in most cases you can replace a flooded battery with an AGM battery, provided the group size, voltage, and terminal positions match. AGM batteries offer better performance and durability, but they cost more. Ensure your vehicle’s charging system is compatible; some older systems may require a different charging profile.
What is the difference between a starting battery and a deep-cycle battery?
Starting batteries (like those in this guide) are designed to deliver high current for short bursts to start the engine. Deep-cycle batteries provide steady power over longer periods and are used in RVs, boats, or solar systems. Some AGM batteries are dual-purpose, but most car batteries are optimized for starting.
How do I dispose of an old car battery?
Car batteries contain lead and acid, so they must be recycled. Most auto parts stores, battery retailers, and some recycling centers accept old batteries for free. Many places also offer a core charge refund when you purchase a new battery, which encourages proper disposal.
