Battery Basics
Warranty

Battery Testing

Extreme temperatures in both winter and summer play a large part in battery failures. Bring your battery into any O'Reilly store for a complete diagnostic check at no charge. We can determine if your battery is about to fail and get you up and going again with one of our Super Start Batteries. If your battery does happen to be bad, we can recycle your old battery at no charge.

 
Warranty

Warranty

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.

 
Recycling

Recycling

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!

 
Core

Core

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.

 
Temperature

Battery Rating

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.
