Thank you very much for your return !
Unfortunately this is the only site that I have also found and I believe that the problem will be the same with every original battery we can found.
Even if a battery is not used its life decreases with time, we have to find an equivalent battery that was recently made, this will be not easy.
Luckily, I have not placed my order.
That's all very good to know about this replacement battery business. Glad my original batch s:flo2 16GB version T51 from MP4Nation is still going strong! Now to find a source of replacement batteries...
Could someone post a pictute of the battery, and the voltage information, etc, for it?
