A very good alternative to an original Sony battery. So far, I could see no disadvantages, so I look at him as a full alternative product. I use this battery together with an original battery in a Hahnel battery grip for Sony Alpha 350. The battery life is doubled and there are no problems in the interaction *. The dimensions are similar to those of Sony original, so you can safely access, because neither problems arise for the charger, even for the camera battery compartment; everything fits properly.
* Why 4 points:
On my last photo tour there was briefly problems in lower load range, but which only rudimentary occurred and an isolated incident showed. Even on subsequent tours showed no problems. I would highly recommend this battery to anyone who wants a high-quality and above all effective alternative to a genuine Sony battery.
