My big impact has a cord never short on power and I'll never buy a new battery. The battery stuff has come a long way and is actually awesome until you have to buy new batteries.
I agree. Batteries only last so long. That IR that I first saw the mechanic use was at the time a top of the line tool and it was exepensive
I will admit the guy used it hard five days a week and it lasted about a year at most.... Everything has its place id say
I have a electric impact that I used in the field to run up bolts and then finished tighten at hand
It came in very handy, used it on pipe flanges that had up to 1 1/4 nuts were I could fit it in, saved time
I still needed to finish by hand and go over often with a slugging wrench
In a repair shop with a good sized compressor id still depend on a quality air impact gun
The first electric impact I had broke the housing one day when I used it and it wasn't like I used it everyday, the replacement I bought is in the bottom of the drawer now
