I use these original battery in my new Panasonic Lumix DMC-SZ 9, because the price difference to the replicas this time is only relatively low. However, the camera takes a lot of electricity (also mentioned in the test report). Unfortunately, the batteries have become smaller with the previous model and so it is best to take it with two additional batteries at least during holiday trips ... In this case, you are in my opinion the original on the safe side.
