I've jsut received some CR2032 batteries in the standard cardboard/plastic packing and a "best before" date of 2022.
The batteries are spares which I expect to use over the next 2 to 5 years or so.
My questions are:
1) I want to check if they are full voltage now. This means breaking the wrapping. Is there anything in the way that they are wrapped which I lose eg inert gas?2) Is there a good way to store them to ensure that they are likely to work when I come round to needing them?
3) Does the "best before" date mean that they need to be installed in whatever a couple of years before 2022?(Yep, I really have nothing more important to worry about at the moment)
