Wow, almost 30 years older than Jesus. You have a treasure man!

Well, mine has 191 charge cycles and it is healty 100% as a toddler.![]()
It's pretty much tethered to a power outlet. One of the reasons I'm considering a MBP13 so I can be 'portable' again.
Wow. I have a 2006 2.16 MBP17. There was a known battery issue and they replaced it right around March '07.
iStat shows health 482 cycles with a health of 65%Barely get 1:30 on light usage and 1:00 if there's a movie running. It's pretty much tethered to a power outlet. One of the reasons I'm considering a MBP13 so I can be 'portable' again

A new battery would be a much cheaper way to get 'portable'![]()
My only concern with the new MBPs would be having to send it away to replace the battery under warranty.
anyone knows why when i plug in my charger, the charge on istat and coconutbattery shows only 98-99%? its only 2 weeks old and i just calibrated the battery. health is 100% so how can my charge be only 99% when it plugged it!!?!?!? any explanation? thanks![]()

it all depends on the work load too. Keep in mind all the factors that can change that.... most people don't use their computers for "light" workloads... i would still expect an average of 6-7 hours on it... which kicks other computers butts that are still stuck at the 2-3 hour range.
Have you tried Apple's conditioning method? Even Lithium batteries need some care. Not as bad as NiCad. If you want the ultimate in bad battery stories, I can show y'all my PB 165c. I've got 3 batteries for that classic laptop. Current health would have to be described thus: I have to plug the 165c in for a couple hours before trying to turn it on. Otherwise there isn't enough power built up to run on AC. Running on battery no longer possible, maybe long enough to boot 25%. (for those unfamiliar, the 165c was the first color laptop, 1991 or so)
There seems to be a lot of misunderstanding in this thread. Most of the "problems" that are mentioned are simply how batteries work. Other than the removable/nonremovable issue, obviously. So, if you don't like it, maybe you should do some research to understand batteries better, at least read Wikipedia for the basics. Or just get a desktop computer.
Lithium-Polymer is a lighter, cheaper, more powerful version of Lithium battery tech than the more common Lithium-Ion. (which basically means it runs even closer to red-line than Li-Ion) That's just standard tech facts, I'm not sure why some aren't trusting that it will last longer, given the same or slightly larger battery size in the new MBP. The excellent software control Apple is claiming is almost necessary just to use LiPo at all, so that's good they have it under control. You wouldn't want a new rash of laptops catching fire. That's been the reason it hasn't caught on quite as fast as the "lighter, cheaper, more powerful" might suggest.
Also, "1000 charges" is the standard industry life expectancy stated for both kinds of lithium batteries. And I mean the battery industry, not laptop. But this isn't a hard and fast rule. It's more like a generalized statement. So is the "500 charges to 80%" expectancy. And it really only applies to full charge cycles, the life expectancy if you have partial charge cycles is basically unpredictable. Which, of course, you will have. (think about: iPod/phone with constant charging in dock or car)
An interesting question to me would be: Who actually makes these LiPo batteries for Apple? Many of us no doubt remember the year of battery horror when Sony's OEM batteries were recalled from virtually every laptop manufacturer, including Apple. What was that, 2005? So, is Sony still making their batteries?
Do not use laptop on ac power with the lithium battery installed. The high temperatures on ac power are the main reason a lithium battery will wear out quickly. So either run you laptop on battery when it is charged or remove the battery when on ac power for extended periods of time. Batteries are chemistry so respect the laws of nature: no free lunch.
Also remember that distance from the WiFi access point and interference issues will affect battery life.

Is this supposed to be a joke?

Apple has made it rather difficult to "remove the battery" in the new models![]()
You don't know what you are talking about. Removing the battery downclocks the CPU. Running off battery all the time prematurely degrades the battery as it has a limited number of cycles in its lifespan. The recommendation is to use 2-3 cycles a week and fully calibrate every 2-3 months.

Sure generalities that are not reasonable measures to take for a vast majority of notebook users. It's obvious that heat degrades battery capacity, but that's kind of the point of the battery. Sure you could keep it in the freezer, but that defeats the purpose of a notebook. The figure 1 is great, but it's showing the loss of capacity after a year of being stored at certain temperatures. Batteries lose charge either way when not charged for long periods of time. It's a theoretical and I'm not keeping my battery in the freezer.

Where did I say keep your battery in the freezer? The advice is to not run on ac mains power for long periods of time when the battery is near 100% charge. Simple. If you disagree, so be it. Be happy paying Apple for a battery replacement sooner than you would have to. Its your money.
