An individual battery unit used as the item-level anchor for battery-passport data.
Battery item is useful for explaining the granularity of a battery passport: the passport obligation attaches to an individual battery record, while some attributes may be inherited from the model, batch, supplier, or manufacturing context.

DIN DKE SPEC 99100:2025-02 — Requirements for data attributes of the battery passport
DIN DKE SPEC 99100 uses battery item as battery-passport implementation context for an individual battery unit, helping distinguish item-level records from model or batch groupings.
Implementation-context summary only; not a verbatim DIN definition. This is a copyrighted standard, so Minespider should use it as standards context rather than republishing the standard text.
Reference: Section 3.25
In implementation, battery item identity helps connect the physical battery, its unique identifier, data carrier, battery passport record, lifecycle events, and dynamic performance data without treating every data point as item-specific.
Battery item is the granularity question behind the passport: which facts belong to this individual battery, and which can be inherited from a model, batch, supplier, or chemistry record. Getting this distinction right prevents teams from duplicating every data point while still preserving the item-level evidence needed for identity, status, and lifecycle updates.
