Title:Life Test for Heavy-Duty Storage Batteries
Issuing Committee:Battery Standards Starter Battery Committee
Scope: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.)
