This paper explains how the lead-acid models described previous paper can be utilized in practice. That paper does not supply detailed information on how to identify the several parameters of the proposed models, and it defines a whole family of models, but does not discuss which model of the family is adequate for a given purpose. These two issues are tackled in this paper. For the first, more complex issue, two options are proposed and discussed: a complete identification procedure involving extensive lab tests and a simplified one that combines information from lab tests and data supplied by the manufacturer. Further simplifications applicable in case of batteries belonging to the same family are presented.
