This camcorder accepted until now only the orig. Sony NP FV70 and FV50 NP enclosed in the camera. I have tried 2 different replicas ... repeatedly "rejected" by the camera electronics. This is the first "Battery replica", which was accepted by this camera. He has a little less runtime (about 10%). However, this term is also dependent on how often I zoom etc. But the price makes up for it! For that I get almost four batteries! A Org. Sony is between 70 and 80 EUR! I would buy it to me again.
