Who makes O’Reilly batteries?

O’Reilly Auto Parts is a major U.S.-based automotive retail chain that sells batteries under its O’Reilly Auto Parts brand. These batteries are not manufactured by O’Reilly itself but are produced by third-party battery manufacturers through white-label partnerships. Common suppliers include companies like Johnson Controls (Clarios) and Exide Technologies, which specialize in automotive battery production. O’Reilly’s batteries are designed for compatibility with a wide range of vehicles and are distributed through its 6,000+ retail stores and online platforms.

How does O’Reilly ensure battery quality without in-house manufacturing?

O’Reilly maintains quality through rigorous supplier vetting and adherence to SAE/JIS industry standards. Partner manufacturers must pass audits covering capacity testing (±2% tolerance), cycle life (≥500 cycles at 20% DoD), and thermal stability (-40°C to 75°C operational range.

Third-party labs conduct destructive testing on random samples—crushing cells to verify separator integrity and overcharging to confirm BMS responsiveness. Pro Tip: Look for the “Premium AGM” label for batteries with calcium-alloy grids that reduce water loss by 80% compared to standard lead-acid. For example, their Group 65 AGM battery delivers 850 CCA, matching OEM specs for trucks like Ford F-150. Why trust outsourced production? This model allows O’Reilly to leverage specialized manufacturing expertise while focusing on retail distribution.
