Optimal u for Sony DSC-HX400V. DSC-RX100 III

I use my cameras like cheap batteries from other manufacturers, and have (mostly) quite good experiences with it. Why? Of course, from the fundamental reason because an original battery for longer operating time is insufficient and original batteries are comparatively expensive. This parameter is an attractively priced and adequate combination. The charger makes a high impression, however the loading lasts a few hours. The batteries themselves have been two charge cycles behind and keep a long time felt through, so it should be. Best Buy!
