How can I check if the battery calibration has been done properly?

I followed Apple's steps precisely, but I see no change in the loadCycles, or battery capacity using CoconutBattery.

Excellent question. Was asking myself how to know I did it right. Your cycle count should have done a +1! –  daniel Azuelos Aug 15 '13 at 15:46

Everything you need should be here: http://support.apple.com/kb/ht1490

There is no indication as such that you've done it 'properly', other than your 'Cycle count' (in System Profiler -> Hardware -> Power) will go up by one. However calibration doesn't necessarily affect your battery capacity immediately; instead it improves the longevity of your battery, and the accuracy of the battery life readings (in your menu bar) when your laptop is unplugged.

You might add that calibration process permits MacOS X to approch a more lower battery level. Hence you have a longer autonomy on battery between fully charged and on the reserve (which is slightly above fully empty). –  daniel Azuelos Aug 15 '13 at 15:42
