Unusually high battery capacity after 300 cycles?

[Beric]

After about 300 cycles and almost a year, I have more battery capacity than I started with when I bought my Macbook!

I just calibrated my battery last night. I have used my computer almost completely from AC adaptor, only occasionally (like right now) using battery power. I extremely rarely discharge my battery completely.

Is something wrong? Do I need to call Apple? I really don't believe I actually have only gained battery capacity after 10 months and fairly heavy use.

EDIT: Also, my real-life battery life seems to be more like 2-3 hours if only using only Safari (absolutely nothing else), and yet my fans really crank up and my Macbook really gets hot.

why are you complaining again?

I don't believe I actually have that battery capacity, and think there is something wrong. I was wondering if there was something I could do to verify my true capacity or something.

Well here is mine after 461 cycles.

Coconut battery isn't very accurate sometimes. Try updating it. For a more accurate estimate, go to about this Mac, more info, click on power, and you'll see the battery's actual health.

Did you follow the exact procedure to calibrate your Macbook?

Did you wait the five hours after the system enter sleep due to low battery?

If you always use it off AC, and rarely use the battery, how can you of gone through 300 cycles?

Yes, I followed the instructions to the letter. I actually waited all night, or 8 hours.

I may just have to try calibrating it again. My battery life is unusually low for just having Safari open.

I think I've gone through partial cycles? I'll use it not charged in at times, and then plug it in a little later. But anytime I'm doing something intensive, like playing games, I plug it in, because otherwise, I get only 1.5 hours of battery life or so.
