Stihl was originally a German Company(West Germany for awhile)
They assemble many of their outdoor power tools sold in North America in VA. I believe VA beach.
The parts come from around the world.
I have a battery operated AK series hedge trimmer I bought three years ago. It was made in Austria. The battery was made in Germany.
They are generally well engineered tools. The only problem is the parts can be more expensive because they are only sold through their dealerships.
I went with the Makita for the battery hedgetrimmer, and am pleased. Both my gas chainsaws are Stihl and one weed trimmer.
“The battery was made in Germany”
Very unlikely the actual lithium cells were made in Germany.
