$@$* battery. All Macbooks clock down a little bit without the battery. The Airs are much more drastic here, they are %#*@ near unusable without the battery. The first five to ten percent works like junk, after that it should be good. If it still works like crap at 100%, try getting a REAL battery and yes expect to pay over seventy bucks for something of worthwhile quality.
