Hello everyone, I just bought my macbook last week from the refurbished Apple Online store, and received it on Saturday from FedEx. I have noticed that the battery only charges to 99% after only 6 charges. It also drops immediately from 99% to 98% as soon as I take the charger out. I have the brightness in the middle so it won't be too bright and too dark, the only things open are Safari and iChat right now. Is that normal? The battery does last its full 8-10 hours though, just checking to see if all this is normal. Thanks guys.
