Comprehensive Life Test for 12 V Automotive Storage Batteries
This SAE Standard applies to 12 V, flooded and absorptive glass mat lead acid automotive storage batteries of 180 minutes or less reserve capacity and cold crank capacity greater than 200amperes.
This life test is considered to be comprehensive in terms of battery manufacturing technology; applicable to lead-acid batteries containing wrought or cast positive grid manufacturing technology and providing a reasonable correlation for hot climate applications.
This document is intended as a guide toward standard practice, but may be subject to change to keep pace with experience and technical advances.
Rationale: This test was developed through an industry sponsored laboratory and automotive fleet study to improve the correlation of test results versus time in the field for a broad spectrum of 12V lead-acid battery manufacturing technologies.
