This paper explains how the lead-acid models described in a previous paper can be utilized in practice. Two main issues are opened by that paper: 1) The paper does not supply detailed information on how to identify the several parameters of the proposed models, and 2) 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 issue, the more complex one, two options are proposed and discussed: 1) a complete identification procedure involving extensive lab tests and 2) a simplified one that combines information from lab tests and data supplied by the manufacturer. In addition, further simplifications applicable in cases of batteries belonging to the same family are presented.
