Original battery is destroyed, otherwise well

Battery and charger do what they should. With a USB Power Pack you can see the empty battery on the go prima load. So far everything well. Unfortunately, I have also tried to load the original GoPro battery in this device. Since this no longer works. Here was something bent mechanically. This is of course very annoying.

Update 03/05/2015:
The Service has contacted me and examined the device. Apparently the contact tiller were too long in my charger. A production error. Did get a new charger. This has now but 4-star worthy.
