This is the longest-lasting replacement battery I've found for my white Macbook. It costs a little more than other replacements but has been well worth the additional $$.
The battery comes half charged when you get it. Easy to replace and charges quickly. Power is great and it lasts as long as you need it (depending on what applications you're running, LCD brightness, wifi, bluetooth, etc.) I have bluetooth, wifi, itunes playing, lcd full, with a browser or word processor on and it lasts about 3-4 hours. I just wish it were 30 bucks cheaper, but otherwise, it's a great product.
