How do I tell the difference between these two country of origins? I just bought some off Amazon that came in a blister pack, but there is no country of origin marking on them anywhere.
In the ones I got from them last year the identification of manufacture is in the finest print on the backside of the yellow card inside the blister pack. To the left of the barcode is a paragraph that states ".. made in China for Energizer Holdings .." on the fourth line down.
