Looking for replacement batteries for my RX10 I now found it. The batteries are even stronger than the original Sony. The camera detects the batteries immediately and they work fine. Although they ought to be nominally stronger, they keep some of the same length as the original battery. That's enough but completely out by 2 days without charge through. On top, there is also an external charger the yes at the camera not included. Everything a very fair price and a product that's in everything in order. That's how it should be ....
