Frequently Asked Questions
What does CCA mean and how much do I need?
CCA stands for Cold Cranking Amps, a measure of a battery’s ability to start an engine in cold temperatures. The higher the CCA, the more starting power. For most passenger cars, 500-700 CCA is sufficient in moderate climates, while 700-850 CCA is recommended for cold regions or larger engines. Check your vehicle’s owner manual for the minimum CCA requirement, but going higher is generally fine as long as the battery physically fits.
Should I choose an AGM or flooded battery?
AGM (Absorbent Glass Mat) batteries are sealed, maintenance-free, and offer better vibration resistance, longer life, and superior performance in start-stop systems. They are ideal for modern vehicles with high electrical demands or for harsh conditions. Flooded batteries are cheaper but require occasional water top-ups and are less durable. If your car originally came with an AGM, replace with AGM. Otherwise, flooded is fine for basic driving in mild climates.
How long should a car battery last?
Typical car battery lifespan is 3 to 5 years, though AGM batteries often last 4 to 7 years with proper care. Factors like extreme temperatures, vibration, short trips, and high electrical loads can shorten life. Regular testing (e.g., at oil changes) can help you anticipate replacement before failure. If your battery is over 3 years old and showing signs of weakness (slow cranking, dim lights), consider replacing it proactively.
Can I install a battery with higher CCA than recommended?
Yes, as long as the battery physically fits in the tray and the terminal positions match. A higher CCA battery will not damage your vehicle’s electrical system; it simply provides more starting power. However, ensure the battery group size (e.g., Group 34, 48, 94R) is correct for your vehicle to ensure proper fitment and terminal orientation. Oversized batteries may not secure properly.
How do I dispose of an old car battery?
Car batteries contain lead and acid, so they must be recycled. Most auto parts stores (AutoZone, Advance Auto Parts) and retailers like Walmart accept old batteries for recycling, often with a small core fee refund if you buy a new battery. Many municipalities also have hazardous waste drop-off sites. Never throw a battery in the trash or leave it in the environment.
