Hello. I have a Whitebook, about 3.5 years old. While the batteries are advertised at newer Macbooks/Pro's to be able to get 1000 charges while still holding 80% battery capacity, mine is older and still gets around 90% at more than 1000 charges. (Screenshot of coconutBattery included.) It might not be 100% accurate, hence the drop to 87% yesterday, but it still keeps the capacity well, might be even better than newer batteries, it seems. Probably I'm misinformed. Please tell me what's wrong with my reasoning.
