MBP full charge capacity
ive had my 15" MBP for almost 2 weeks now from (even though it say 2 months on age of mac on coconut batt.) anyway i calibrate my batt. yesterday since my batt capacity say 6500 mAh and im getting only 6239 mAH and 95% battery cap. After calibrating it last night it went down to 6132 mAh and 94% this according to coconutbattery:\ is this normal?

I get discrepancy between Coconut and SP. I think with those numbers you're fine.

Here's some light reading on the subject:

Also here's how to keep it calibrated properly according to Apple.

i would have to say that i have been real lucky with this battery. all i can say is keep them cool and they will last a long time ;)

but i do remember a time when it was at like 83% and it came back up so im not sure what that was about :Confused:

I got 5468mAh but mines only a couple days old, I have charged it maybe twice including calibration.

All times are GMT -4. The time now is 06:51 PM.
