    Hi Guys!

    Have my macbook about 24 months now, and this past six months the charge is not as good as it use to be. It now holds just over an hour worth of charge.

    Also when set to show remaining charge as time, it can function a bit weird, for instance, right now, for the past ten mins it was saying 44, 43, 45, and now it has went to 32 in the past two minutes.

    I have calibrated a few times, but may try this again, as it has been a while since I done this.

    According to apply if it seems to have bad functioning whilst under 300 charge cycles it can be replaced!?


    Charge Information:
    Charge remaining (mAh): 1288
    Fully charged: No
    Charging: No
    Full charge capacity (mAh): 2743
    Health Information:
    Cycle count: 251
    Condition: Check battery
    Battery Installed: Yes
    Amperage (mA): -1959
    Voltage (mV): 993

    So what you think, is this normal?

    Forgot to say, it shuts down (does not sleep) at 20%! It is still under warranty (another year left).

    Normal. Get ready to replace the battery. $$$

    For comparison (I just got this battery this week as a replacement to a battery with issues):

    Full Charge Capacity (mAh): 5383
    Remaining Capacity (mAh): 3364
    Amperage (mA): 1771
    Voltage (mV): 11959
    Cycle Count: 2

    I'm getting about 4 and a half hours on a full charge with my screen a bit dimmed and no music playing. If I change either of those I do see a dip, but it is what I'd expect.
