Battery Safety - two wrenches on the same battery

[clayman]

Last year, I accidentally shorted one of the 2010 batteries with a hacksaw. The gigantic shower of sparks was startling enough, I was lucky the hacksaw didn't end up welded to the terminals

hence why the nut goes to the inside when I do batteries. that way the screwdriver is only near one terminal at a time.

i sometimes have help but i always have the second person work on the same terminal as I am.
