I own a Macbook pro 5,5 13" from late 09'. Just today I noticed that my battery life indicator is showing a 'Service Battery' warning. I suspect that the problem is either diminished capacity or swelling due to the trackpad often sticking. My question therefore is: How much will it cost (preferably in £) to have the battery replaced? I did purchase Apple Care with my mac back in July 2009, however I have heard that this does not include replacing batteries. Also when contacting Apple, will I have to provide any proof of Apple Care or can they look this up through taking the serial number of my mac or personal details? This is an issue as do not have the Apple Care box with the details on it at hand. Thanks.
