    I just revived my MacBook Pro (Late 2006) after it being dormant for a few years. The battery condition is "Replace Now", but it's health is apparently 72%? How accurate is this, seeing as I see many others here using it? If you unplug the machine, the computer just goes off.


    This is the second battery its gone through since I got it. :rolleyes:

    I'm sure some will not hesitate to correct me.. However it appears that your computer is disabling the battery. If it won't charge while it's plugged in.. I'd replace it. Anyway, goodluck!

    Just a thought!

    Leaving a computer dormant like that will kill the battery. It should be pulled out and recharged every few months.

    FYI, you can get the full battery information using the built-in System Information app. No need to use CoconutBattery.

    Batteries don't last forever. Leaving it unused for a few years will likely kill most batteries. coconutBattery has had some accuracy issues with the age of your Mac, but otherwise is pretty accurate. I prefer iStat Pro. Once the health drops below 75%, it will show "Service Battery" or "Replace Now". I recommend you buy a new battery.

    This should answer most, if not all, of your battery questions:

    If your battery doesn't charge, then it doesn't charge. That's much more precise than coconutBattery :D

    On my MacBook, mid 2006, second battery, if the machine gets unplugged by accident, there is plenty of time to plug it in again without excessive hurry. So the battery lasts for at least ten seconds :D But I think not using the Mac for long time will definitely hurt the battery. I'd go on eBay and look for a used battery if you don't want to payout for a new one, just to cover accidental unplugging.

    When I got the "Replace now" notice, I ignored it. My understanding is that the only issue is lower battery life - it's not going to wreck anything. If you can cope with lower battery life, then you can save yourself ~$100 (for now). Also remember that your 2006 MBP computer is only worth around $300... .

    Well, it's dead now. The machine can't even see it anymore. That's okay considering I'm just using it for light surfing and editing for when I don't want to get out of bed.
