It's Japod, described as 1350mAh. I ordered this: http://www.dealextreme.com/details.dx/sku.32398 4 months ago, and it works well. I even get the impression that it lasts longer than the original Nokia battery; certainly good value for money. I've been using it since I received it, and have not noticed any deterioration. Japod appears to be one of the better battery brands. I would recommend it.
