I have a 2006 MacBook, 1.83ghz. The battery is swelling and is now completely useless as the metal connectors no longer touch due to the bulge. I know this is a bad sign so I took the battery out and don't plan on using it anymore. This is past the 3 years that Apple warrants the battery, I believe. Anything I could do to get a new one from Apple sans cost? If I were to buy a replacement, should I buy Apple branded or third party? Do they make batteries that last longer than the stock Apple ones? Thanks!
