Hygrometerstand for AA Battery

I my filament boxes some of these round cheap chines Hygro+Thermometers are mounted, more than 10. The battery life of the small LR44 only few months - perhaps cause of the cheap quality.
Now I test it by using a AA battery - normally a lower price.
OK you have to solder two short lines red for + black for -.
I solder it directly to the battery poles - you need a good heat and soldering paste, I recommend fine sandpaper for removing oxides. Longtime heating the battery is not as good.

For some devices I could need this stand which I ve created now.

Don't know if there is someone out in the world to need this too - enjoy!
perhaps you visit my youtube channel to find diy videos and perhaps you'll improve your german, like I do with english videos.
