I think it's a fair question - hardware companies have recalled and replaced dangerous components before. I got a free replacement battery from Apple in the mid 2000's when they said that a batch of their batteries had a "small fire risk"... If I'm being cynical, I guess it depends if their line is: "the old battery is dangerous which is why we've changed the materials we use" or "we're changing the materials we use, and that has this interesting side effect that totally coincidentally fixes a dangerous issue with out old batteries"
