Me too. I got it resolved ... eventually.
Hi,
I first noticed my battery was bulging on Friday, Sept 3, 2010. I called Apple Care on Saturday. The representative tried to convince me this was normal and nothing to worry about
but that maybe I should think about replacing it ... maybe I should bring it to my local service provider. He said they had very few reports of batteries bulging (this I did not believe).
The battery is just under 2 years old, and it has had 132 cycles. The battery still charges fine -- at least it was last week!
I live 2 hours away from the nearest Apple Store, so going there is not feasible. I took it to a small local Apple Service provider today, September 7. They said it should definitely be replaced, but that it wasn't under warranty, and I'd have to buy a new one. I was pretty irked with that, especially after all I'd read here.
They didn't have one in stock. I wasn't going to leave my computer with them for several days while one came in. They did suggest as I was leaving the store that I call back and ask for a Customer Satisfaction representative. I did. It was a long irritating conversation. My argument: a battery that loses charge and gets weaker -- that's a battery that has worn out. This is a battery that is bulging, a potential fire hazard. This is a defective battery. I had to continue making my argument for a while. They insist this is normal wear and tear (maybe it is normal, given how many people have had problems with them!) Even if it is normal, I don't think this is right. This is a defective battery. I am not sure how much time I spent on the phone today between arguing as calmly and pointedly as I could and sitting listening to awful music on hold; it was a long time.
Apple did agree to send me a new one at no charge, in the end.
I hope anyone reading this who has a bulging battery has better luck dealing with Apple (time wise, though I did get the result I wanted) than I did.
