I just want to start off saying I am somewhat of an apple fanboy and I also am a proud of owner of a unibody macbook, fast forward to a few days ago when I finally decided to do something about the fact that the battery was swelling so much that the aluminum flap would no longer close. I set up an appointment at the genius bar at my local apple store and head there. I tell the gentleman my problem give him my serial number he informs me my laptop is out of warranty and that the best he can do is offer me a replacement for $99. the price doesnt bother me so much as the fact that this is a defect in the product and potentially dangerous. I thought about mentioning the class action lawsuit from a few years ago but decided to try a different avenue so I thanked him and left. I called apple care and again received the same answer that I would have to fork over 129 for a new battery, no discount this time. At this point I am upset and give up for the day and try to convince myself that I should just go ahead and buy a new battery. Some point the next morning I decide that I will call apple again and not take no for an answer. This time the customer service rep was much more friendly though no more helpful he scheduled a time for me to go to a different apple store so I went to this apple store fully expecting to have to make a scent to get a new battery. Alex who was my genius that afternoon asked my name and what my problem was and then told me to wait for a minute. He comes back with a new battery unwraps it puts it in my macbook to make sure it fits and tells me to have a nice day. I said all that to say thank You to Alex at the apple store. Also this is my first post here sorry it was a bit long but I wanted to thank everyone on this forum for providing so much information regarding the expanding battery so I knew some people were getting replacements and others werent.
