This SAE Standard serves as a guide for testing procedures of automotive 12 V storage batteries.
The ratings submitted are to be based on procedures described in this document. The ratings submitted must be of a level that when any subsequent significant sample is tested in accordance with this document, that at least 90% of the batteries shall meet the ratings. The choice of 90% compliance recognizes that batteries consist of many plates and require chemical-electrical formation procedures and small variations in test conditions and procedures can affect the performance of individual batteries.
Future Considerations - In order to expedite the release of this revision of the Standard, several topic areas were deferred for consideration in future revisions. These items include, but may not be limited to, the following: post dimension modifications and a new, more application relevant charge acceptance test.
This document applies to lead-acid types of storage batteries used in motor vehicles, motorboats, tractors, and starting, lighting, and ignition (SLI) applications which use regulated charging systems.
This document provides information updated since the prior revision issued May 2011. Areas included are document references, adding citations for Twenty Hour Capacity Test, SAE J3060 Automotive and Heavy Duty Storage Battery Vibration, and SAE J2981 Starter Battery Identification and Classification, adding/revising procedures for temperature control during Charging and revising the recombinant/AGM Charging procedure to provide greater consistency of recharge and to improve alignment with other international standards and specifications. In addition, the Vibration Test, Terminal & Hold-Down definitions and drawings have been removed and are included in SAE J2981 Starter Battery Identification and Classification and the J3060 Automotive and Heavy Duty Storage Battery Vibration test standards.
