You recharge CR123 primaries???

I also have 15 years old Energizer CR123 still going. My guess is the L91 (AA) uses the same technology as CR123 and after 10 years they were still good and the manufacturer decided to print the labels with 20 year shelf life, I don’t think they changed anything in manufacturing to make them last longer. Probably the same with CR123 except they still come with 10 year shelf life printed. But, 30 years? I don’t know.
