Hi Mike!

I'm going to put my 2› in; may be the same answer as Ed's, may be 
something different and we'll all learn....

I'll put tape over the positive terminal of used UPS batteries so 
something won't connect, possibly create a short circuit and catch fire.
....Thinking about it a flimsy piece of Scotch tape isn't much of a 
barrier; packaging tape, duck tape (I think duct tape is metallic), is 
thicker and so less likely to be sliced open.  

AA, AAA, C, D's I just put is a small box with the positive ends 
towards the cardboard -- negative terminal to the center of the box.  No
complete circuit made.

9v batteries make things interesting: both terminals are on the same
end.  Putting in the box with the terminals against the carboard is
fine: cardboard is non-conductive.  (Ky's thinking 'yeah, unless it gets
wet'.)  My thinking is putting tape across the terminals lessens the
possibility of making contact and creating a circuit.  I'm not sure what
the storage in a mayonnaise jar does other than a _glass_ jar if sealed 
would minimize air -- limited oxygen for any fire and the glass might 
remain intact during any brief fire.  The new plastic jars would also 
minimize available oxygen but certainly melt.

.... I sympathize with batteries: I never get included in anything either.
