It may not be of much help to you, but I recently upgraded the original Toshiba 250GB HD in my late 2008 unibody MacBook with a 750GB Western Digital Scorpio Black HD.  After replacing the HD I noticed that when I checked the System Report under Power it showed that the battery had completed 166 cycles and the battery condition was showing as 'Service Battery'.
To the best of my memory I had never seen the Service Battery message before.  In fact, my battery was replaced by Apple about twelve months ago (I believe) as it was one of the faulty batch of batteries that developed 'battery bulge' .  If my memory is correct my Apple Care 3 year contract had already expired by then (I purchased my MacBook in November 2008) but the battery was replaced free of charge because the Serial Number of my MacBook corresponded to those with the defective Sony battery.
Since then I have been careful to follow the advice from Apple regarding maintaining the battery in optimum condition.  I was therefore surprised to see that, after 166 cycles, my battery only retained 72% of its original capacity.  I downloaded CoconutBattery app. to check this.
Yesterday I followed the advice of others on these forums and re-set my system management controller (SMC) and also re-calibrated the battery.
I don't know which of these worked but my battery is now showing 'Normal' and, according to CoconutBattery app it now has 79% charge.
Perhaps it might be worthwhile for you to do as Bimmer 7 series suggests and also re-calibrate your battery - it can't hurt!
