Power for the star tracker!

Perfect for the star tracker (laser pointer Class 4B)! Lasts a long time and has great power. Tested at a 80 pages-school block the laser burns with a focus on 0.5mm and at a distance of 10cm with these batteries after a good 10 seconds completely (also the board and front).

Reach with these batteries enormous! Nearly 5 kilometers further than with Varta Lithium Batteries (tested in laser pointer PowerMeter - has received at 22km light from the laser at Varta only about 17km). 10 Batteries should keep for my Starseeker several years, have 2 batteries have been receiving it and there is still no power reduction measure.
