If this happened within a year I would simply insist they replace the battery under warranty and highlight that there was no element of discretion about it. They would do it.
I did insist. I don't remember the details anymore because it was a couple of years ago. I would have taken them to small claims court over it if I had been in the US but I was overseas long term. Either way, they have lost a customer who has bought many of their laptops over the decades. Over a $100 battery that clearly had a manufacturing defect.
