**Description:**A battery specifies a set of observations. These observations typically have a logical or practical grouping for generally accepted clinical or functional purposes, such as observations that are run together because of automation. A battery can define required and optional components and, in some cases, will define complex rules that determine whether or not a particular observation is made.
\nExamples: "Blood pressure", "Full blood count", "Chemistry panel".
