Battery Basics


Warranty begins on the date of purchase and expires at the end of the warranty period stated on the receipt.

Should these batteries fail during a free replacement period, O'Reilly Auto Parts will replace it at no cost to the original purchaser. Any battery that fails as a result of misuse, abuse, low fluid level, freezing, improper installation or another faulty part are not covered by warranty.



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!



Some products have a core charge associated with them. A core is some portion of a part that can be recycled or reused by the manufacturer. For this reason a product with a core has an additional charge associated with it.

If the old part is returned in reusable condition (either to one of our stores or shipped back to our online store), the core charge will be credited back to the card used to purchase the part. Please note: It is the customer's responsibility to pay any shipping cost associated with shipping a core back to the O'Reilly Online Store. There is no shipping charge if you take the old part back to one of our stores.


Cold Cranking Amps (CCA)

CCA 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. 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.
