>increase the risk of a fire substantially
The article doesn't state by how much it increased.
>You realize they stopped selling them, right?
I don't think Amazon is an authority on battery safety and are airing on the side of safety than making an actual judgements on the safety of it.
No they are definitely not. You’re completely correct! They are, instead, an authority on what might get their asses sued to the moon and back and apparently found the cost/ benefit of selling this popular product to be negative. Any ideas what might cause that?
That lower than .5 mm margin on those edges may not have caused fires - yet - but if nothing is done about it then one day they will. That's an accident waiting to happen.
