This SAE Recommended Practice applies to 12 V, automotive storage batteries of 180 min or less reserve capacity. This life test simulates automotive service when the battery operates in a voltage regulated charging system. It subjects the battery to charge and discharge cycles comparable to those encountered in automotive service. Other performance and dimensional information is contained in the latest issue of SAE J537. This SAE Recommended Practice is intended as a guide toward standard practice, but may be subject to change to keep pace with experience and technical advances.

This SAE Recommended Practice applies to 12 V storage batteries which operate in a voltage regulated charging system. It simulates heavy-duty applications by subjecting the battery to deeper discharge and charge cycles than those encountered in starting a vehicle. The deeper discharge and charge cycles in service may come from a combination of the following conditions: a Frequent occurrences of total electrical load exceeding the alternator output. b Frequent occurrences of battery system supplying the electrical loads when the engine is not operating. c Frequent occurrences of prolonged vehicle storage combined with high vehicle key-off loads. Batteries will be classified into two types for this life test. Type 1 applies to batteries with reserve capacity of 200 min or less. Type 2 applies to batteries with reserve capacity greater than 200 min. (“C” value for Type 1 equals 25.0; “C” value for Type 2 equals 50.0.)

This SAE Standard serves as a guide for testing procedures and as a publication providing a record of current production batteries, their ratings, and container description. Any battery with planned significant usage may be submitted for inclusion in the Tables of use. (Reference Section 5 and Chart A1 of the Appendix.)
