I bought the 1.6ghz 120gb HDD model Air on Monday. I ran whatever little charge is in the battery down to nothing, left it off for 5 hours, then charged it for a full day, well past the time when the magsafe turned from orange to green as I was at work. Upon turning it on the battery health was 95%. I rebooted and still no change. I calibrated, ran it down playing HD shows on hulu.com, left it off from 8 pm to 6 am, then plugged it into a power source from 6 am to 5 pm. Battery is at 95% health still. I'm assuming this is not normal, am I correct?
