Store used button cells
Where do you stay with used but not empty button cells? Especially now after the Christmas season, many accumulate only slightly discharged button cells.
Bags are not attached, which can touch the button cells. So what was closer than taking something like the original packaging? My idea was bubble wrap! So as seen in the picture:
Carefully scrape the upper side of the blister in the middle. The air escapes and there remains a pocket of just the right size for the flat batteries. So the "flat" can be stored wonderfully until next use.
