It's getting to be budget time again and I'd like to replace our Milwaukee battery operated sawzall's (on the rescue trucks) with a sawzall that is able to run more than 5-7 min on a full charge.
We do have 110 on the trucks and can run a corded sawzall, but I've herd that somebody had a sawzall that can run on both AC power and batteries & was wondering how good of a deal that is.
We have replaced the Milwaukee sawzalls batts a couple of times, but they wear out and build up a memory & when it's cold out or under a heavy load (like cutting the roof off a F350) they wear out before the job is done.
So, do the tool experts here have any info on sawzalls
