I have several batteries from different brands for my Panasonic Gh5, but only two from Fujicell. I used them only for one season as the second ones were completely unsuitable for professional use, as the terminals oxidized and when they supplied power to the camera, it was very likely that they would suddenly stop doing so, causing the camera to turn off. Often, they don't even supply power to the camera. They were also continuous during charging, both using the genuine Panasonic chargers and those of other brands such as Jupio. I no longer consider them part of my equipment! I have left them aside and replaced them mainly with Jupio batteries, which currently seem reliable. Literally, they are garbage!!! Stay away from this specific battery!!!
