Battery operated tools

I've had a battery-powered DeWalt sawzall for many years and loved it. However, even with extra batteries on the sidelines, I can outrun them while cutting branches up. I am not impressed with the life span of their batteries and man, they ain't cheap either. I bought a new HD Milwaukee 110v cord type and called it a day. I thought my battery DeWalt was cool but this Milwaukee is badass and has tons more power and no more work stoppages, waiting for batteries to get charged up. Oh yeah, and if those batteries were a little too hot, they wouldn't allow it to be charged for another 10 or 15 minutes. Done.
