Does this look weird to anyone?

Why would a battery one day out of the box only be capable of charging to 6808mAH / 6900mAH?

Could it just be a matter of the battery not being calibrated yet?

It could just be CoconutBattery. It sometimes has trouble correctly reading the newest machines.
 
Will do. What a pain in the a$$ process calibrating is... I probably won't do it until tomorrow night at this point.

If anyone has an i5 and can check theirs, I would appreciate it.

As far as it being CoconutBattery, iStatPro is reporting the same thing.

It's probably a calibration issue... I hope.
 
Hmm... It also says that your computer is 123 months old. I didn't know i5 was around in 2000. Ha.
 
System Profiler is also showing the full charge capacity as 6808 mAH...

The readings are never 100% accurate. Your battery capacity will fluctuate up and down over time. It's not unusual at all. You're fine, as long as it doesn't drop below 80% within 300 cycles.
 
I calibrated it and am still not showing 100% capacity... Still hovering at right around 98%.
 
My Macbook

My 2.3 year old Macbook always showed 100% until about 2 weeks ago. It showed steady 98% for about two weeks then now shows 95%. System profile say it's in "good" condition, cycle count is 56. iStat shows 95% fully charged and 99% mark for "health".

I'm thinking my battery "condition" has just peaked and now started to "dip". My Fujitsu Lifebook I've had for over 6 years I never even thought about the condition of the battery (but then it doesn't show the charge percentage figure nor do I use it much w/o the AC plugged in.)
 
Full Charge Capacity

I've been reading this and other threads about battery life and noticed that most Full Charge Capacity readings are 6800 or so. Mine reads 5752. Is that an issue or do these vary all that much?

Which model Mac do you have? The newer MBPs have built-in batteries that have higher capacity than the removable batteries.

This is a brand new 13'' MBP. Just arrived on Monday.

When I first ran Coconut Battery, it showed pretty much exactly the results from the first post.

Since my first calibration, the Current Battery Capacity went up to 7170 mAh; the Original Battery Capacity stayed at 6900 mAh.:confused:

15" i7, hi-res antiglare model.
 
is this right??? :confused:

My first charge was 101% (6989) my next charge was 99% (6850),this is how battery works, they varies a bit from charge to charge.
The same was the case with all my previous laptops.
As long as it stays within 95%-105% don't worry.
 
I did my first calibrate last night on my new i5 and then let it rest today until the magsafe indicator went green then booted up.

Still at 97% battery capacity at 6710/6900 mAh. Oh well. I guess it's close enough.
 
Coconut Battery is buggy as crap. Look at the screenshots, it says original battery capacity is 1300 mAh. That's like an iPhone's battery capacity !
 
i tried that and mine still says 13000 mAh full, current is 12971, why is mine so high??

the probably just reused one of the old apple exploding batteries. no worries. j/k

I wouldn't worry about it. If you have problems with it, apple with fix it.
