      A123s in particular you have to be very careful about. There was a defect a few years back and thousands of cells were discarded with the tabs snipped. But they ended up on the Chinese market with newly welded tabs, and they're always trying to unload them on unsuspecting victims.

      Could these be the one? I have never seen A123s sold without tabs before.

      Those are almost certainly from those batch. There are thousands of them out there, many with new tabs welded on. they have a bad habit of getting this weird mark on them and then ballooning.
