    when i use my mb battary, it doesnt last 5 min before it shuts itself down. why? i have coconut batt and i have used 10 load cycles since 2 years ago ans will shut down when indicator reads 93% or around there

    any ideas? is my batt just really bad since i dont use it much?

    upon further inspection, i see the battary SLIGHTY bulges ner the center. would this be causing it?

    is this a recognized issue or am i screwed and have to get a new batt? or what?

    ive had this mb since mid july 06 fyi

    I would stop using it immediately and remove it from the computer. There is risk of fire and explosion. Then bring it back to an Apple store or similar and buy another one.

    no i havent calibrated it recently. howevereach time i unplug it and let it run, it will run longer than previous (i think)

    i did the power management reset and the batt update firmware

    however, i saw this as well
    http://www.apple.com/support/macbook_macbookpro/batteryupdate/

    seeing how i bought mine JUST over 2 years ago, looks like im out of luck. think i should call anyway?

    edit: system profiler says my battary condition is good with a cycle count of 30, not the 10 coconut batt reported

    Do a calibration and take it to the store. See what they say and then you can decide what to do. I would personally change it, since a deformed battery (even if slightly) is usually a sign that something is wrong internally.

    Keep us informed!

    how do i calibrate it? the computer just shuts down at random batt levels when running off it. aka i cant run the batt down to 0% charge

    this just sucks as i dont have applecare and this seems to be a pretty big defect imo

    ugh

    Well, I must say that 10 cycles in 2 years means you haven't used the battery much and that may be the cause of the malfunctioning. At least a cycle per month is what Apple suggest.

    As I already said maybe at the store they can tell you more about that program. Just give it a try.

    crap, taking the batt out makes my macbook run at like half speed.

    i go from a geekbench of 2500 to 1300 with the batt out

    not cool. not a cool way to start morning lol

    Yeah, it's due to the fact that to run at full speed the MacBook will draw power from the battery if needed. Without battery it will reduce the speed to avoid power loss.

    I called apple and got a replacement battery for my Macbook even though it is over 2 years old. I didn't pay for the call either because they said they said i could ask a few simple questions without getting charged. Basically i had the issue debugged before i even rang and explained that to them.
