Hi Chuck:
I don't think it's possible with a BA-5590. There's circuitry inside
that limits the current draw with a dead short. Fully draining the
battery is no problem, in fact there's a one way action switch on the
BA-5590/U that puts a resistor across each internal battery in order to
fully drain it.
You may be thinking about Li-Ion or Li-poly batteries where fire comes
out of the battery when it's mistreated (too much current either charge
or discharge, over or under voltage, or mechanical puncture). Like the
video at: http://www.valence.com/SafetyVideo.asp
Not true about LiSO2 batteries and commercial products. The "D" cell
that's inside the BA-5590 is used in a number of products, medical
emergency equipment and head mounted flashlights come to mind.
Have Fun,

Hi David:
You might consider getting a BA-5590/U military battery, see:

These are really two seperate batteries, each one made up of 5 LiSO2
cells, 15 volts per battery, 30 volts if connected in series.
These are primary (not rechargeable) batteries with a shelf life well
in excess of 10 years. (I have some 14 year old units that test at
100%) Between 170 and 210 Watt hours depending on which manufacturer
and date you get. You need to be extremely careful NOT to charge them.
You must also be extremely careful NOT to fully discharge, or short
circuit them. If you do, explosion, or explosive outgassing of Hydrogen
Sulfide
gas is a very real failure mode.
There are very good reasons why LiSO2 batteries are never used in
commercial,
or consumer equipment.
