Medtronic specifically recommend FR6 lithium cells in their insulin pumps. https://data.energizer.com/pdfs/l91.pdf https://data.energizer.com/pdfs/l91.pdf https://www.medtronicdiabetes.com/sites/default/files/library/download-library/user-guides/MiniMed-780G-system-user-guide.pdf https://www.medtronicdiabetes.com/sites/default/files/librar...
