It's fine

It is doing a trickle charge to 100%. That way it doesn't over charge the battery. You'll be fine.

It won't overheat your battery. :) Also, only charging to 99% is not uncommon. Here's another thread with info: http://forums.macrumors.com/showthread.php?t=420954

and to keep an eye on your battery condition, just click on the Silver Apple, and click on "About This Mac" next click on the "More Info..." then click on "Power" and scroll down just a bit and you'll see:

Full Charge Capacity (mAh): 5403
Charge Remaining (mAh): 5403

Cycle Count: 1

These are my stats, and I keep a close eye on them almost to the point of obsession! :cool:
