[NEED HELP] These strokes drives me crazy

[FreDiabetics]

I'm tryring to recreate these thick strokes for a battery bar on my watchface. illustrator naturally changes the strokes automatically when the contour is enlarged. I know thats a basic question. can anybody point me in the right direction? do I have to create a custom stroke to change the size to avoid the automatically changes of distance and size? 

Thanks for any hint and advice 🙂 have a nice weekend

Draw them like this:

Then expand the strokes and punch them using the pathfinder panel.
