Generic said:You got the date code backwards, it's March of 2011. It's funny, I just took apart 3 packs of these. One pack was "recycled" and had dremel marks on the caps. One pack was all 0V, and 1 pack had cells between 1V and 2V. I believe these are re-wraps of used cells, but I don't have proof.
