Description
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.
Ratings Compliance
The reserve capacity and cold cranking at -18 °C ratings submitted for battery performance capability are to be based on procedures described in this document. The ratings submitted shall be of a level that when any subsequent significant sample size is tested in accordance with this document, that at least 90% of the batteries are expected to meet the ratings. The choice of 90% compliance recognizes that batteries consist of many plates requiring chemical-electrical formation procedures, and small variations in test conditions and procedures can measurably affect the performance of individual batteries.
Applications
This document applies to lead-acid types of storage batteries used in motor vehicles, motorboats, tractors, and starting, lighting, and ignition (SLI) applications that use regulated charging systems. This standard was originally developed based on traditional ICE usage, thus other applications or usage profiles could require alternate or additional testing.
