Is Apple Hardware Test Accurate?

It is reliable, but sometimes batteries reach their end of life. It won't necessarily appear on the test, you just have to get a new one. I suggest bringing it to an Apple Store first so they can perhaps swap out the old one with a new one, just to make sure it really is the problem, before purchase.
AHT has missed things before that my AASP later ended up finding. And I should mention that we've had quite a few battery / charging / power problems on the 2012 MBAs at work (we have 200).
Reset your SMC and make sure you've installed firmware updates.

Excuse the ignorance, but how would I know if I'm current on the firmware updates? Have upgraded to Mountain Lion, current on the "software updates" that i review weekly, but have a feeling there may be something I'm missing here....
