Can my previous negative votes only agree: the supplied battery GoPro can I charge and there is (at least no perceptible) self-discharge instead. In this here (yes would also have to be original) I invite the battery fully, but if I want to use it (eg 1 week later), the Cam can not even turn on! -> Total emptying. When charging process, the battery shows the usual display activity.
The GoPro battery _is_ inherently weak in the chest (max. 1-1.5h), which is known, but not so! Definitely not buy recommendation.
