something is wrong right??
seems about right for 266 cycles
might want to check into this.
That's not what it should be. It's supposed to be 80% of original after 300 cycles. For all you people not so good with math, the capacity now should be 4400. The 814 value they have puts it around 15% of original.
i've got the model number matched...not the serial number
Have you tried calibrating the battery?
I have around 216 cycles (on an 18 month old machine) and still retain about 80%
Overcharging with the computer off supposedly contributes to this. If you keep your laptop on (even in sleep mode) it keeps the current moving through the battery, rather than gathering up. I've had my laptop for 9 months, I use it daily, and it retains a 95% charge.
However, please correct me if I'm wrong about the battery.
try the apple battery exchange if that doesnt work buy a new one.
Well, technically it says "up to" 80% capacity, which means that even 0% capacity is acceptable.
I have a powerbook with ~350 cycles on it, and still have ~80% of my original capacity. Have you tried recalibrating lately?

I imagine the one one the left will apply (since you've ruled out the link on the right)
how much actual battery life do you get??? could most likely be an error. recalibrate the battery.
Coconut battery says I'm at 90% after 439 load cycles.
This is the battery that I received because of the recall, so it's about a year old.
last night i let the battery drain...then it went to sleep mode
this morning i turned i plugged it back in and let it charge...thats recalibration right??
here are the results:..so sad
wow tahts sad man. u poor fella i have a better life than that with both cores at 100% and dual screens
Perfectly normal to have the results in the RED.
Common sense test... Q: What do you think?
They Replaced It!!!
That's a Good Answer...
My Oldest battery is 225+ cycles (1 1/2 yrs.) and near 90% (88-93 typically) today... I usually "sleep" my MBP and Kill and Calibrate it every 4-6 weeks if I can... Treats me pretty good so far...
