SAE J537_202309

This SAE Standard serves as a guide for testing procedures of automotive 12 V storage batteries. The information contained herein was originally developed based on traditional ICE operation but can be more broadly applicable to other vehicle architectures. Although the test procedures contained herein are written from the standpoint of a 12 V nominal battery, they can be scaled for batteries with different nominal voltages. Traditional internal combustion engine (ICE) vehicles comprise the vast majority of the global car parc in operation today. While new vehicle production is migrating to more advanced drivetrain configurations, including start-stop, the ratings and test procedures developed for the 12 V batteries supporting the traditional ICE architecture are often still applicable to the more advanced systems. Furthermore, maintenance of standards related to batteries for traditional ICE vehicles is critical to support the full life of those vehicles through multiple rounds of maintenance and component replacement. Other documents have been, and are being, developed to provide more specific guidance regarding batteries utilized within more advanced drivetrain systems, such as SAE J3012. The procedures detailed within this document were primarily developed to support traditional ICE vehicle operation but are often more widely applicable.
