Battery - BlackBerry Torch 9800

Battery is perfect, seems to last longer than the original. Although the descrption isnt clear, because the original batteries seem to be coded. This item comes with a device to duplicate the code which is great, but requires the original battery to do so, making the product useless if you are purchasing the battery because you have lost the original. Dont think this is made clear on the description, Although it didnt affect me because I had the original battery it may affect others.
