Hot Application Cycle Life Test for Automotive Storage Batteries 1999-01-1084

The current SAE standard for an accelerated laboratory test, J240b, does not comprehend the high under hood operating conditions of modern automobiles. The SAE Automotive Storage Battery Standards Committee commissioned a Task Force to develop a new test standard. Their objective was to develop a test that produced failure modes found in high temperature service and that took less time, A test development strategy was developed and carried out by members of the Task Force. The results indicated that running the current test, J240b, at a higher temperature, 75°C produced good results for batteries constructed with book mold cast grids but not others.
