Just re-calibrated after it not being calibrated in 3 months, and the health went from 93% to 87%. What gives? Ideas?

First, you don't need to calibrate your battery. Second, calibration doesn't change your health; it only makes your readings more accurate. This should answer most, if not all, of your battery questions:
 
Not sure whether or not this applies, but you have a relatively low cycle count for a computer that is likely more than a year old.

Yea. It's my secondary. For the most part, when I use it, its off the charger, and when I don't use it, it's on the charger. I've read the battery info section. Just seems odd to be at 51 cycles which is extremely low and already be at 87% health.

Batteries will die quicker if they're not regularly exercised. It's better to run on battery a few hours every few days, to cycle the battery more often.

It could be due to the fact that you use it so infrequently, but if the run time per charge isn't noticeably affected I wouldn't be too concerned about it.

Age will also eventually kill your battery, even with 0 cycles.
 
Well thanks all for at least calming some of the paranoia :) :apple:

I'll try to make sure I use it a bit more :)
