The external mounting of batteries for bench devices is a good idea, Hue.
I've
taken to putting a small ziplock bag around the 9v battery in
multimeters, etc. The wires come out through a small opening in the zip
end, but otherwise the battery is sealed and wrapped in plastic. I'm
hopeful it will contain the leakage and reduce the damage, including the
corrosive vapors from the batteries I've seen damage whole areas of pc
boards and components.
