title: Discharging Time Series of a CR2032 Battery at 11 mA

description: Scope

This record contains raw data from the constant-current discharge of a CR2032 lithium coin cell at 11 mA. The test was performed using a BioLogic battery cycler with data recorded at 1-second intervals. The CR2032 cell is manufactured by VARTA and was tested in ambient laboratory conditions. The dataset is intended to demonstrate ontology-based linked data reporting that is also consistent with the FAIR principles. RDF metadata is made available in json-ld and html formats.
