Required safety practices are also included. These recommended practices are applicable to all stationary applications.
Initial performance parameters are the key properties of a lead–acid starter battery. These are the total energy or capacity content and the ability to be discharged with a high current at low temperatures to start an internal combustion engine.
The charging method is another key procedure in any test specification. Most documents follow the approach that it shall be ensured that the lead–acid battery is completely charged after each single test. The goal is that the testing results are not influenced by an insufficient state-of-charge of the battery.
