Since I bought the camera Sony Cyber-shot DSC-HX9V, it was necessary to have a second battery to cope with intensive energy demands of this device (even without GPS). Just as the use of 1080i video (which gives excellent rendered), puts it very quickly flat. Admittedly, this is a battery a little tight at autonomy. Sony played miserable with this accessory. Anyway with two batteries can not be surprised in the same day. This is a necessary insurance. In addition, the order of this article passed from Amazon brings us this battery at a reasonable price compared to what we see on other sites and the harbor is very fast.
