The laser pointer has been supplied with a CR123A lithium battery, which has already been charged.
For those who think they have got a defective laser: You should probably turn around the supplied battery cell, because this was not properly loaded in the factory around accidentally activate the laser to avoid during shipping.
The device has an extremely high capacity of approximately 45 MW. (Laser class 3R - Keep out of reach of children.)
An IR filter is installed, however, so there is no risk of fire.
After I unscrewed the head portion of the laser, I have something movable laser module with a few drops of epoxy resin on the inner housing is fixed so that the solder joints by vibrations can not be too much stressed. (But is not strictly necessary.)
The laser unit is not intentionally called by me as a "pointer" as it may not be used as a pointer in Germany because of the very high performance. The use of a laser sighting of weapons (even toy weapons) in Germany is a breach of the War Weapons Control Act.
