Hi

There is no exact rule on this. The only way to figure it out is - open the packet and look for the MV output. The manufacturer (E.g. Teledyne) claims a shelf live for around 2 years for the R22D.

I had some O2 cells in an unopened packet completely dead 7 months after the production date. I also had a cell working fine after 12 months.

I change all cells together on a regular basis. This is at the end cheaper than buying a lot of spare cells which you can't use anymore.

Kind regards
