Delivered the battery in a pretty little box. It is matt and grippy. A Quick Start Guide is located in the package. The battery works like most conventional batteries. A different color is always displayed by repeatedly pressing the button.
I have presented the battery a long time ago and he has since been in daily use. The user is very happy with it and has confirmed that the battery lasts a long time.
The only thing that is certainly not appeal to everyone, that the battery is just a little thicker and heavier.
Hot the battery in use is not. When charging it is a little warm.
