WARNING CAUTION! PLEASE WATCH. It can easily happen to you.
Hey Brainiac, Steel wool will do that with almost every battery. That has been widely known for many many many years! It is not just Dewalt Batteries!
Yep. Remove the battery (takes two hands - can't fall out by accident); then put steel wool across the live unit electric contacts and guess what? The steel wool catches fire!
I'm guessing that if you put in a drill bit, put it against your shoet and pull the trigger, it will make a hole in your foot!
When man invents a foolproof machine, nature invents a bigger fool!
