Cell / component only. A manufacturer claim, not a listing or certificate. Printed as "Terminal UL1973 Cells & UL9540A Intertek Certified Complete Assembly (ETL)." in the Certifications paragraph on Volthium's own product page (51.2V 100Ah Rackmount Battery – 5.12kWh ESS, volthium.com, captured on October 20, 2026), where the page sets "Terminal", "Cells" and "Intertek Certified Complete Assembly" in bold, so "UL1973" reads with "Cells". The page adds "If the application for CSA certification is requested at the time of order ($), the batteries will be delivered with the CSA UL1973 label affixed.": a CSA UL 1973 label on the battery is an option at order, not the standard product, and is not recorded as a claim for this record. The technical sheet the record also cites is titled for the Self-heating version and is not used here; the "UL9540A ... Complete Assembly (ETL)" wording does not say what was tested and is not recorded. No issuer, certificate or report number is printed; the issuer's record was not checked. Cell scope: a claim about the cells does not certify the assembled battery.
