This review is from: cellePhone PolarCell battery Li-Ion for Nokia 5800 XpressMusic / 5230 / C3-00 / N900 / X6 8GB 16GB 32GB / Asha 200 201 ( replaced BL-5J ) (Electronics)
to my surprise the battery has held up pretty well in a N900. I don't have to always charge my phone. I would say that its worth the price compared to other batteries I have tried out.
