My pbook doesn't have that option in system Profiler.
Does the pbook have to be plugged in to see the "power" tab?

One can get battery information in 10.3.x by running ioreg utility from Terminal:
mac:~/$ ioreg -c AppleMacIODevice | grep IOBatteryInfo

| | | | "IOBatteryInfo" = ({"Capacity"=3984,"Amperage"=202,"Cycle Count"=254, "Current"=3984,"Voltage"=12575,"Flags"=1090519047,"AbsoluteMaxCapacity"=4400})

My 15" PowerBook is 8 month old. Battery've lost around 9% of capacity:
(4400-3984)/4400 after 254 cycles.
 
Same laptop same issue... went from about 3.5 hours of juice to 20 minutes of juice .... all in 111 cycles. bullshyte i say. This is a 2000.00 computer not a 500.00 walmart special. I don't think i expect too much... just a battery that lasts for as many cycles as apple claims it should.
 
Full Charge Capacity (mAh): 3616

thats mine, rev a powerbook, dont know if it is good or not though.

This is from my 12" Rev B (1Ghz), but I swiped my SO's battery from a Rev C (1.25? 1.33?) about 2 months ago. (My original battery now only goes for about 2 hours... Will have to capture its stats sometime.)

(and yes, I did get my SO a new battery. Eventually.) :D

I'm scared to use my ibook because of the battery death!

however Coconut battery says

Its a revision c powerbook, i got in about 3/4 months ago new. I allways change the battery full and then drain it dead..... Is this good or bad. I cant figure out what my numbers mean, what do they correspond to and why are they different.
 
I have no idea what happened to my battery but it is really sucky. It lasts under 20 minutes :( All those numbers you quote make me jealous!

Rev B 12" PB. On the power cord most of the time (especially since it turned crappy).

I've got a Rev B 12" also and by battery sucks ass:

Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1714
Remaining Capacity (mAh): 1704
Amperage (mA): 0
Voltage (mV): 12390
Cycle Count: 326

My battery is supposed to be a 4200mA, and its 22 months old. Just wondering would replacing the battery solve this crappy battery issue or would that one die a short death also ?

Another command (for 10.3.8 and later) that's shorter than the one posted earlier:

in Terminal,

ioreg -w0 -l | grep Capacity

My 19-month old 12" rev-D PB -
Cycle Count: 116
Absolute Max Capacity: 4400
Capacity: 3828

I guess a 13% loss after more than 1 1/2 years isn't bad.

Terminal - bash said:
$ ioreg -w0 -l | grep Capacity
| | | "IOBatteryInfo" = ({"Capacity"=3828,"Amperage"=0,"Cycle Count"=116,"Current"=3742,"Voltage"=12471,"Flags"=838860805,"AbsoluteMaxCapacity"=4400})

In Danish, but you know the system:

Batteri installeret: Ja
Første advarsel om lavt spændingsniveau: Nej
Fuld ladekapacitet (mAh): 7091
Resterende kapacitet (mAh): 7064
Strømstyrke (mA): 0
Spænding (mV): 12385
Antal cykler: 294

This is after 2 years of use. Seem to be ok when I compare to other stats in this thread. But I think I'll be even more carefull now to remeber using the cable.

Well, 535 cycles and it finally went down some more, now its at 2069 for full charge capacity. I'm thinking when it gets down to 1500 or so I will bother to get a new battery. Should be another year or so my guess.
 
beat this:

5 year old lime iBook 366, original battery
battery when new = 3600mAh

Full Charge Capacity (mAh): 2632
Remaining Capacity (mAh): 2630
Amperage (mA): 0
Voltage (mV): 16500
Cycle Count: 15


pretty good after 5 years of solid usage I'd say :D
 
Battery Information:

Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 3865
Remaining Capacity (mAh): 3655
Amperage (mA): 0
Voltage (mV): 12477
Cycle Count: 139

That seems to sound good but in practice, I can only get about 20 minutes before my battery is dead. It was explained to me the individual cells in the battery can quit, which explains why these pieces of rubbish go from 87% charge to shutting down with no notice.
 
my 1 day old 17", hehe!

kwajo.com i hope the battery on this baby is as good as yours!
 
Jeeze, with about 1/2 year usage I'm down to 4100 from 4200...that seems pretty bad to me. 61 cycles. :(
 
Wow Im absolutely horrible with my iBooks battery, but since it does go EVERYWHERE with me, (I think the longest I have been with out it outside of school is for 4 hours). 133 cycles, when Ive had it since black friday (so 3 1/2 months)

It's only a piece of rubbish if someone treats it like a piece of rubbish.

The most common way to kill a battery's cells is this:

1. the battery runs out
2. the computer falls asleep
3. the computer isn't plugged in before the sleep light turns off (in other words, it completely shuts down)
