I recently took my Macbook Pro (early 2008, not unibody) to check out the battery health to a Apple authorized repair place (MacXperts) and this is the second battery that I've had that's had to be replaced because it went bad. 1st battery: died within 30-40 minutes 2nd battery (current): caused by MBP to shutdown when there was plenty of battery left. It basically went dead with no warning. Now I'm waiting on my new, third, battery. Now, my questions: Can this be actually be caused by my Macbook Pro? Or are we looking at a fairly common issue and I've just gotten two bad batteries?
