MacMerc.com has a full story and updated picture (via way of flickr) of a MacBook Pro battery swelling far beyond any size it should have originally been.

The battery is a model A1175 that should have been exchanged when Apple began its program in response to overheating and swelling found in the MacBook Pro battery series earlier this year.

Apple states that there's no physical danger from using the swollen batteries and it's still safe to use the batteries until a replacement unit arrives from the company.
