at storaging .Why are repair shop using air tools instead battery powered
tools.

1] Habit; they were taught with air tools
2] They don't care a whit about efficiency
3] Seen a 300ft/lb cordless impact wrench lately?
4] electricity+gasoline=bad

Partly true, but the big ones in the auto shop environment are cost and
durability. Air tools are much more durable than most battery powered
tools, and their cost relative to their performance is low since the
real power source for all those air tools is one big compressor and it
is directly providing mechanical energy to the tool.
