I'm using two that are rented a little. I've looked under there pretty closely and determined in all my vast battery experience </sarcasm> that they aren't dented down enough to be dangerous. They aren't close to touching anything. And I no longer use the mod I believe to be responsible. Also, they don't get used in any mech mods.I think it's my page, yes.
Those aren't my batteries, my statement stands.
It's possible that any vaping product that applies too much pressure can dent the battery, yes.
It can be dangerous, an important distinction.
The denting has to be bad enough for that battery, and the situation, for it to move from possibly dangerous to actually dangerous. There is no data on acceptsble dent size, depth, etc., available as no denting is acceptable for any of the other commercial/industrial applications for these cells.
I don't know how common it is but I'm guessing there are at least thousands of cells like those in that picture being used by vapers.
