Anyone else at/around 20 battery load cycles?

My 4 month old battery has 40 load-cycles and it's down to 89% health, but it was at 93% health at 39 load-cycles, so I'm gonna have to call apple up eventually I think.

Yeah, yours does seem a bit low. I also did the battery update even though I didn't seem to have a problem. (17")

mine is doing pretty well...

This is a Rev.A CoreDuo Macbook Pro 15"
I had my battery replaced as part of the initial recall right before all the HUGE recalls that everyone remembers. This new battery is doing pretty good, huh?

edit: if i calibrate first, will i get better or worse battery life in coconut? i haven't calibrated since the first time i got the battery.

I was thinking of replacing my battery too..
it was 91% before i calibrated it.

Wow, I beat all of you.

iBook G4

It was purchased by the original owner in Feb 06, I bought it used in Nov 06.

Damn you guys always have your laptops plugged in?

Damn it, i really need to get a new battery; im down to 16% capacity! How much do they cost these days at the cheapest? Its for a PowerBook G4?

And so on...

I did have to replace my Powerbook 12" G4 battery last year... it ended up lasting about 30 minutes, but it was 2 1/2 years old at the time, so it had had a good innings.

I'm now just disappointed at how much longer my girlfriend's MacBook battery lasts than my C2D MacBook Pro...

Wow... my macbook is on 8cycle. and already 4852capacity 93%, original 5200mAh

97% 15 load cycles 6 months old.

I just checked my ibook's and its had 536 battery load cycles and capacity is down to 34%. I got it second hand back last August and it had about 90% capacity then - guess I shouldn't use it as a laptop as much!!

My girlfriend's that was bought at the same time still has a good 4 hours of battery life in it while mine only lasts an hour or so these days. Hers is her only computer though and she usually uses it plugged in at my desk while mine's my travel buddy so is usually running off the battery. I've definitely noticed the battery life drop sharply in the last two months though. Before then I used to get 3 hours with the brightness on minimum.

94% health after 27 cycles & 5.5 months - about average i think.

93% Health. 48 cycles. I've had it since January. It's a 15" CD MBP.

I've got a C2D 15" MBP at 20 cycles and 98% battery health. That's what iStat Pro tells me anyway.

Istat pro shows a different value as coconut battery

Here is my info for what its worth. I seem to be doing rather well.

I know this is PPC, and therefore perhaps slightly different, but I calibrated mine the other day as it seemed quite high. Although I have a couple of hundred load cycles, it still seems to be well over 90%, so TraceyS/FL, it's probably worth keeping a careful eye on yours before the warranty's up.

My PB G4 has nearly 500 cycles and is still holding 81%.
