Would you dare to use this cell?

I got a horrible delivery from alibaba with banged up cells and in one case a leaking cell. All of this can be blamed for insufficient packing by an unserious supplier.
Anyway. One cell has a bent terminal. The internal resistance and voltage of the cell match the other three cells from the same box, but I'm hesitant of using it or even capacity test it. May this issue result in internal short, or dare I use it?

NO ! DO NOT USE ! The terminal is straight the pad itself has been twisted inside the cell, it IS screwed, not useable, the "jelly roll" inside is now deformed and that will only end badly. Leaking Cells also DO NOT USE !
 
Thanks Steve, you confirmed my suspicion, I will not use it!
Regarding the leaking cell, I had no intention of using it!

Also I have no intention using this cell where the internals got shifted: ?

sorry to hear that those cells were rendered unsafe to use by physical damage :confused:

thank you for documenting

hoping your project may still proceed soon!?

Thank you. Yeah, I'm doing an extensive documentation for the dispute, including capacity testing of all cells. It's a tedious process but I'm not letting this go. I will post the full story and documentation in the near future.
