    It has been plugged in for 2 days straight sitting on this table. Maybe unplugged for 20 minutes in the last couple days.

    ... this is my battery?? Is this thing a dud?

    OK the pictures work now, but I don't see what the problem is. Your battery has 34% charge remaining and your machine is plugged in. Your pictures give zero helpful information. What is the problem?

    Try calibrating it, running it completely down then charging til it's 100%, its possible all you need to do is calibrate, still have probs talk to Apple.

    The problem is that it has been plugged into AC the whole time.......

    I didn't notice because I was making tutorials and then once i started rendering it out, I went omg.

    So problem = Ac + 33% battery..

    Aren't you supposed to stay fully charged when you are plugged in?

    I think what the OP was trying to say was that he/she has only unplugged the machine briefly for 20 minutes or so, yet the battery is down to 30%.

    OP, how long is your battery life normally?

    And if you were doing any video rendering in that time that would've most definitely killed a lot of your battery.

    I haven't unplugged it today, I was simply saying 20 minutes over the whole weekend really. It has been plugged in AC for at least 10 + hours without any kind of small break.

    I take this to work with me everyday, but I keep it plugged in there too. I haven't ever really used the battery except I calibrated once.

    Try running the battery completely down and cycling it back up again. Then restart it. If that does not help search Apple support documents on how to reset pram on the i5. You should make an appointment for the Genius Bar just in case you cannot fix it yourself as you can always cancel that appointment. Sometimes my macbook gets stuck on a certain battery percentage until I unplug the power supply and let it drain a little and then it picks up where it actually is.

    You also may want to try resetting the SMC, can clear up weird battery issues.

    Correct behavior would only see perhaps 97% at the most. You must calibrate your battery properly and return with the results.

    Well I didn't calibrate, but I did do a PRAM reset and restart. Battery was still at 33% but charged up normally. Now I have it fully charged.

    No idea why this happened.

    Calibration is a monthly maintenance, it's not too late.

    agreed, calibration of the battery is a important monthly task if you want your battery to last you for awhile.
