Part of processing cells is checking for damage. I have processed about 2K of cells so far, and a handful or so were seriously damaged. Just a glance and you could see the cell was crushed--into the bad bin.
A couple had a scratch, a serious scratch. The scratch was beyond just the PTFE sleeve--into the bad bin.
I have also come across a dozen or so cells that were like this:
Not a huge dent, but enough that if you get it in the light right, you can see it. To me, a dent is a dent--into the bad bin.
This dent almost seems like a manufacture dent, as there is no way it could be caused by being in or the taking apart of the pack. Maybe it was done by whomever made the packs, I don't know.
What level of dents do you accept?
Again, to me, dent is a dent, it is impacting the jelly roll inside in some way, no way for me.
