Perfect replacement battery!

Works great and fits perfectly. Although it is NOT an official brand battery, it works good as a replacement. It lasts long and was half the price. The one thing it is missing in the battery indicator button. It doesn't have a way to know how much juice it has like the original battery did. But, as a backup battery, who cares.
