But you have to bear in mind that the quality is far below average. In my Victorinox Digital eg while working the screen, but not the backlight. Lt. Manual is that for about 1/3 to 1/2 battery power. Have tried all 5 batteries, with the same result. For "Varta" or "Energizer" by the way everything is easy.
Conclusion: OK for flashlights and other things with more frequent and easier exchange counter. For technical equipment, which can then each time needs to adjust, I would recommend more quality.
