    hi guys
    in short my MBP battery is bummed.
    399 cycles and holds charge for about an hour.
    bad i know but i have had it under a year.....

    here are the system profiler details:

    Charge Information:
    Charge remaining (mAh): 2013
    Fully charged: No
    Charging: No
    Full charge capacity (mAh): 2594
    Health Information:
    Cycle count: 399
    Condition: Good
    Battery Installed: Yes
    Amperage (mA): -1524
    Voltage (mV): 11651

    so i am thinking it might be defective in some way, can i get a new one without spending £100?

    Once you reach the "300 cycle" mark, they aren't very inclined to replace your battery for free. I doubt you'll be able to convince them otherwise but it wouldn't hurt to state your case, you never know. :)

    ...How did you manage to drain 300 cycles in under a year anyway?? That would be one cycle everyday (including weekends) for 300 days!? :eek:

    Im fairly amazed that you've managed to get through 399 cycles in less than a year, thats nearly impossible, however it seems you did. Unfortunately as your battery is over 300 cycles the chances of Apple replacing it are minimal, but you could always pop into an Apple Store and ask a genius. You could try explaining that the laptop is under a year old, and that its covered by warranty for a year, but he may just throw the 300 cycle cover only back at you.

    One final note, did you try calibrating it recently? And you calibrated it as you should when you first bought the laptop right?

    I would try calibrating it and see if anything changes
    Charge to 100%, disconnect from AC and use normally (ignore the "reserve battery power" indication) until it turns off and hibernates (breathing sleep light). Let it sit for 6hr or overnight and recharge in the morning and allow a full recharge.

    If you live close to the shop then it won't hurt to go and ask. Go while your charge cycle is still lower :D
