Cameron Sino replacement batteries - Thoughts?

[Vaardu]

I have an old Nokia smartphone that I wish to use again and perhaps others, I don't throw away many electronics because they still have use left. The problem I have is the batteries. There are many battery replacements for Nokia smartphones, and in this case, a Nokia E90 Communicator. I have one, and the original battery isn't in good shape now and was wondering if anyone has bought a CS branded battery from eBay?
