wtf is up with dat. I have a 17" PB and 98% battery
Is this normal

capacity question
the capacity is refer to the max energy it can store.
the amp, for physics we all know.
The strength of a current of electricity carried by a conductor.
what i do with iPod and iBook are:
1-iPod, use it until it drains
2-then try several times to turn it on(knowing it will not play) in order to keep the HD running
3-switch is always ON (and u'll heard a noise in the HD)
4-until it the noise is over, I recharge it
5-takes 2:30 hr
this is once a month
usually i do 1 to 3 and it takes 3 hrs to charge
I get 6:30 hrs to 7hrs everyday on the walk
iBook battery:
1-use it until it goes to sleep
2-the i plug the AC and remove the batt right away.
3-and when i go to sleep,
3a-I let it go to sleep with the battery only until the light is off (normally 3 nights)
3b- i turn it off and charger it
3a also once a month,
2/5 i charge it while using.

Li-ion batteries don't like it. NiCads's on the other hand love it. 3yr old TiBook lloking at 2294 here.
2.5-3 hours
the 98% seems right. Current is current level of charge. 58/59~98%
Not sure of the units on any of these. I imagine that they are equivalent so that if you divide capacity by amperage you get a rough sense of battery life.
iBook 500 Dual USB (2001)
capacity 2919 amperage 1200
My second battery already! The first one only lasted about a year before it gave me a mere 40 min of plain surfing (screen dimmed and all). I have had the second one for about 18 months now and again it is down to 1 h 30 min (from approx. 2 h 30 min). Well, it's certainly an improvement over the first one.
Let's face it: Apple has a weak spot here. My 10 Gig iPod will also need a "heart transplant" soon.

Re: ATTENTION, Battery Life Info POLL.
Can you tell me which PB 15" that is? I have the newer Aluminun (FW800) 15" and I know they have a different Battery Encloure (I don't know about the internals). I've been using the battery no more then 10 hours a week starting in Nov, and I'm showing
"IOBatteryInfo" = ({"Capacity"=3769,"Amperage"=1200,
that's a far cry from the 4600 you have listed. At this rate it won't last a year

Hi.
This was interesting to read, I've only been getting about 1 hour on my TiBook 550's battery. I was getting 2 hours and then all of a sudden it dropped to an hour.
When I check mine out I get 'Capacity=1198, Amperage=1040". It's over 2 years old and has gotten a lot of use so I'm not complaining really as I've had my money's worth really. I'm not sure why it might have just dropped like that though recently, maybe it's just on it's way out. Those figures dont look good!

on my 12" pb, i have Capacity"=3125,"Amperage"=1200 ... i get up to 3 hours on a single charge... what gives?... the meter says 1:50... great......
My 2 year old 14" iBook 600 scores a whopping 673. It goes for about 45 minutes if I'm using airport and have the screen at full brightness. I miss when it could go for five hours. Maybe it's time to buy a new battery...
If you want your laptop to avoid mine's fate, I usually left it plugged in whenever possible (and overnight all time time), but would sometimes let the battery drain enough that it turned itself off. I also accidentally knocked it off my desk while it was running so that it landed face-first onto a concrete floor and broke its hard drive, and then took it apart myself to put in a replacement. So don't do that.

My 1.5 year old 12" iBook 600, on AC and fully charged, only shows:
Capacity: 2445 Current: 1200
I get less than 2 hours out of it, and always have. I've always suspected I had a bum battery. Do people really get as much as 5 hours, as Apple claims?!? How can there be so much variation in batteries?
With the AC unplugged, I get the following:
"IOBatteryInfo" = ({"Capacity"=2445,"Amperage"=1011,"Current"=2347,"Voltage"=11874,"Flags"=4})
Can anybody decode all those numbers? What are 'Flags'?

700mhz iBook, 1 year old--but battery is 1 week old (AppleCare didn't send the original battery back after service so I got a replacement).
Capacity"=4729,"Amperage"=1194.
I get over 4 hours, with AirPort on and the brightness on the display turned up. Other power management is stock battery setup.

CORRECTION
I must say that i was wrong about the capacity.
Today I just did the montly drain and after full charging I got 4608 opp. to 4578 at first.
I noticed that lot of ppl say they never reach the 100% mark when charging.
I always reach the 100% every time I charge and it drops to 99% after 30 to 60 minutes. if the AC stays plug.
I also notice lot of ppl saying about calibrating, how do you do that?
The scores given by MacAddict are the latest books. Therefore, ibook G3 and Tibook values are unknown for me.
However, I do believe that the ibooks share the same battery. and the Ti's battery is superior since Apple said that:
Ti : 61-watt-hour lithium ion battery that provides up to 5 hours
and Al :46-watt-hour lithium ion battery that provides up to 4.5 hours
therefore, Ti generates 5 watts/hr more than Al
I noticed that my ibook g4 12 used the first 20% in 55min. and this is with airport and lot of activity monitoring apps on.

ioreg -l | grep -i iobattery
i noticed that droppin capitals in this command it's ok. so u can just enter:
ioreg -l | grep -i iobattery
which is way faster.
notice that checking every minute, changes nothing butthe Amp. so don't wast ur time.

I have a question that is kind of related to battery life so Im going to go ahead and post it in here instead of making a new topic. If I up my RAM from 256 to 640 on my iBook, that would mean I wouldnt be using as much virtual memory, so it wouldnt have to access the HD as often. So then I would save more battery power correct?

Once or twice I almost got 6 hours but that was running a dim screen etc.
Watching a DVD its about 2.

this is from a 1 year old 17pb
is this normal, or is somehting wrong?
thanks andreas

In Theory...Yes.
In Practice... ?
Apple lists the screen brightness and HD spin up as the big power mongers (aside from apps that use intensive CPU and 3D card use). So I would suspect that more RAM, causing less HD use, would help. Now, how much power RAM uses compared to HD? I dunno.
Somehow I doubt that you'll save much more then a few minutes though, if that. If you were to save more than that, I would think RAM manufacturers would start claiming this in their attempts to sell RAM
Thanks Earendil. Unfortunately I wont be able to tell because by the time I have the extra money to buy the 512 stick from crucial my battery life will have already gone down from everyday use. Anyway, as I posted above that when i re-calibrated my battery the capacity went from 4144 to 4545, do you guys think its worth it to try and re-calibrate it again and see if i can get any higher?

Voltage=16729 (YIKES!!!)
Got a PB Ti 667 15", 2Yr. Battery has been bad since a year. Colleagues here with the same machine bought at the same time also lost most of their capacity. This is ennoying, and makes the battery almost useless, especially when we want to use the airport. Seems like this is an issue with these models. Anybody wants to comment? Feedback would be appreciated. Solutions: even better.
