Battery Rating

Battery Ratings at O'Reilly Auto parts

Reserve Capacity (RC), Cold Cranking Amps (CCA), and Amp Hours (Ah)

Reserve Capacity is the number of minutes a fully charged battery at 80°F will discharge 25 amps until the battery drops below 10.5 volts. The higher the Reserve Capacity, the greater the staying power.

Cold Cranking Amps is the rating that identifies your battery's ability to start in cold temperatures. The rating refers to 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 greater the starting power.

Amp Hours measure battery capacity by multiplying the amount of Amps by the hours of discharge. For example: A battery with 120Ah rating can provide 1 amp for 120 hours or 2 amps for 60 hours or 3 amps for 40 hours or 5 amps for 24 hours or 6 amps for 20 hours, etc.


What is a battery core?

When you replace your car's battery, the battery that was replaced is called a core. Battery cores are returned to and recycled by the manufacturer. A new lead-acid battery can consist of up to 80% of recycled materials and contains 99% recyclable material. The proper recycling of batteries is good for the environment, reduces the cost of batteries and is regulated by federal, state and local laws.

  • Nearly 200 million pounds of lead are recycled annually
  • Over 12 million pounds of plastic are recycled annually
  • Over 6 million gallons of acid are recycled annually

Don't just leave those old batteries lying around. At O'Reilly Auto Parts, it pays to recycle your unwanted automotive batteries.

Just bring them into your local store and we will give you a $5 gift card* for every automotive lead-acid battery you bring in, even if you didn't buy it from one of our stores!
