And this is how you write a PROPER report on the issue: http://www.szilveszter.ca/blog/archives/447
Note that I've contacted both Engadget and Cult of Mac, urging them to write on the matter. There is likely a software issue here as I've had this warning creep up during late developer build testing. Previous SL builds showed no such message. There is more going on here than dying batteries I guarantee that.
All faulty battery or software aside, this issue seems to be about more than just a bad battery. Many users are facing problems. Whether their batteries are covered or not, this signals a serious issue with Apple battery quality.
Batteries should last more than 1.5 years, or 2 years. Even if the battery is under warranty, and its shown that SL is accurately reporting the status, why are the batteries failing?
I purchased a Mac for a considerable amount of money. I expect quality in the parts. To date, I am on my third battery (one was part of a global recall, while the other was shown faulty). Now this one needs to be replaced (if SL is accurate) in 1.5 years?
The bigger issue is why is this happening?
"... and secondly, and this is the most important, the sudden shut down with no warning at all when battery is still 50% or 60% or even 70% (seems random)."
Yes, this is the most important issue for me too. I have no confidence in my battery, and dare not use it unplugged anymore. I shall try booting from the Leopard disk when I get home from work later, and see how long it lasts then, and see if I too get the low-battery warning as it is supposed to do.
Here is what I think, we will wait for a resolution, and indeed, if there is no resolution we will just need to buy a new battery, but this is what I think we need to do, and I encourage everyone to do so:
If we need to pay for a battery, as those batteries will run down quite fast, we just need to be sure that just before the year warranty of that new battery, bring to them, and get it tested, and as it will show is in bad condition, get a new one under warranty, and next year the same.
So, if my suspicious are right, either we get a software update soon that fix the problem, or we get a new battery for life for the price of one, so not a bad deal right?
I disagree with the Unofficial Apple Weblog guy, and others. I have taken care of my battery, and the battery stats I posted some time ago prove that. This is a software issue.
Luckily, I haven't experienced issues such as random shutdowns and the like. My 'Service Battery' issue is more of an annoyance, and comes and goes as it pleases. If it's a straight battery issue, and the software was fine and working as conceived, the battery would show 'Service Battery' at all times.
Some more research and results, I did try before booting in 64bits as someone suggested, but at that time, the "Service Battery" message didn't disappear, so I though it did nothing, well, this time, I have used this program:
You just need to be sure your computer model is within the list.
It will allow you to save the 64 bits booting so you don't have to press 6 and 4 every time, and the result so far is good, message "Service Battery" still there, which we can probably just ignore for now, but good things is, I didn't have any random shut down for now, fingers crossed it keeps like this! will post if anything changes.
So do we still need more proof to demonstrate there is something wrong within the OS?
Yeah, it seems to have been a bit longer a couple of times, but now seems fine, will keep an eye anyway.
I knew also I should have wait a bit longer before my post!! I was actually replying, my battery went to 10%, good, got the "Low battery" alert, good, but then a minute later it shuts down with no warning, is not suppose to go to sleep??
Once is fully charged I will try again and see if I can get at least to 10% again.
Please post here if any of you guys get any improvements booting in 64 bits, the annoying message may not go away, but see if it shuts down and when, hope we can get to something, even on our own.

After experiencing the service battery menu as I reported earlier I tried recalibrating my battery several times. Randomly it started to work ok even after going to sleep, but then low and behold service battery at 70% and then within 2 minutes it dropped to 0%!!
Charged it up and booked a genius bar appointment and guess what - was working fine and 4 hour battery time!! Genius plugged in the ipod nano and checked the battery and reported the battery is fine! He was very sympathetic and explained that the OS can flash the firmware in the battery and perhaps this is what has happened, although he said that this was the first case he had come across.
Anyway as soon as I got home guess what, service battery menu appears again!! Bit the bullet and bought a new battery and no problems!!
My suspicion is that snow leopard has flashed the battery in some way that is causing it to respond incorrectly the the computer's polls for battery status. As the genius explained to me he expects there to be an update to fix this sort of thing as it has happened in the past.
Since running the 64-bit app above, I have drained the battery down. As I write, it is at 13% for the first time since installing SL, and I have had the low battery warning!!! Ok, it didn't take long to get there, so my battery has indeed seen better days. But no random shut down!! Can't believe it.
Thanks for posting the link Bullet618- noticed it on my RSS after you posted. After waiting this long, I am so disappointed TUAW are treating us like we are all idiots.
There are some good points mentioned there, to be fair:
1. Monitoring in SL is now where it would be noticed more, before point of no return.
2. How many people monitor their battery's health?
3. Apple's new diagnostic tool measures battery health NOT through the same computer it's used on. That might help to isolate a fault in the SMC or elsewhere in the target machine.
As to the rest... Ah well, he clearly says the opinions are his own, not Apple's. Caveat emptor.
