    Batteries don't maintain their factory condition forever. It just doesn't work that way. From what I've seen, your numbers don't seem too unusual. Unless there is any loss in battery life that is significant enough to affect your ability to work and enjoy your computer, it shouldn't be a concern.

    Do you really consider that a problem?? My battery is at the same health as yours after some 16 cycles.. And after calibrating.

    Your battery is perfectly fine. As you use it, it will gradually loose some of its maximum charge. There is nothing you can do for it.

    As for this:
    As far as I can tell, you're describing the calibration process, which, despite what you might have thought, will not "improve" your battery. It will merely display the correct charge when you use it.

    If you're suspicious, go to :apple:>>about this Mac,>>More Info...>> and then under the "hardware" tab, select 'Power.' It should give you some information on the condition of the battery if you scroll down a bit. :)

    I'm confused, do you mean the battery will come loose and not fit securely or do you mean it will lose charging capacity?

    Are loose and lose two different words in the UK? Here, one means something doesn't fit properly, and the other means to misplace something. For example, If you lose 10 Kg your jeans will be loose.

    i am just dumbfounded at the moment. can someone enlighten me to how they are doing this?

    such low load cycles on an 8 month+ mac whilst at the same time the battery is charging while no charger is connected? hmmmm

    coconutBattery must just like to mess with people like me :confused:

    Yeah, Coconut has really been a disappointment. I loved it under Tiger, but it's unusable for a lot of users with Leopard. However, like I mentioned before, there is a work-around:

    I have iStat but I found its battery meter to be unreliable (even under Tiger). I often got readings which were worse than what they should have been. However, without Coconut, I've been forced to use iStat, and I've noticed that it's gotten better compared to before.

    That screenshot is of the app called Coconut Battery. Otherwise, follow the steps I listed out earlier:

    go to :apple: >>about this Mac,>>More Info...>> and then under the "hardware" tab, select 'Power.' It should give you some information on the condition of the battery if you scroll down a bit.

    Isn't it possible to take the battery out while you're plugged to electricity? Batteries have a limited amount of charge cycles, so if you don't need to use them (i.e. when you're using the computer as a desktop) you should be able to remove them in order to save charge cyles, and make them last longer. It's possible with other laptops

    thats what i do... also keeps the laptop cooler/quieter as without the batteries the mac slows down the processor.

    That isn't recommended for long term use because the CPU will be crippled without the battery. Since the battery doesn't go through very many active cycles while on AC, there's really not much to gain from unplugging the battery. Even with regular use, your battery will last a fairly long time (probably as long or nearly as long as the computer itself if you replace computers every 2-3 years).

    I was on the phone with apple and they decided to give me a new battery since this one is being a pita. full charge capacity of 2145 mAh is normal after 2 years of ownership?
