I am wondering if Apple changed the form factor of their MacBook (Pro) batteries since Early 2008? I was planning to replace my broken MacBook Mid 2010 Unibody with a used MacBook Pro from early 2008. However, the battery life of my MacBook 2010 was ~4-6 hours still, where the battery of the MacBook Pro I am interested in only lasts ~2 hours.
So, it would be nice if I could simply swap the batteries. Unfortunately I didn't find that many infos on the battery shape and compatibility.
What I read here was that the battery of the 2008 Pro has 60 Watt, and the battery of the 2010 MacBook model has 63.5 Watt. I am not sure in how far these 60 Watt might be just an approximation and if not, if it could cause problems.
