I got a package of a 100+ recycled and tested 18650s from batteryhookup (blue LG's), and about a third of the cells have a dented positive terminal. Some of them also have a small dent in the negative terminal.
Luckily the dents dont seem too deep, I'm pretty sure I can still spot weld them without trouble.
But should I worry about it? See photos: https://imgur.com/a/s07GGaZ
