I recently dissected a depleted Duracell(tm) MN1604 9-volt alkaline 
"transistor" battery to recover the snap connectors.  I was surprised to

find that it contained six cylindrical cells smaller than AAA size, 
connected by spot-welded stainless steel straps.  Most similar batteries

contain wax-covered stacks of flat rectangular cells. The cylindrical 
cells are individually insulated and can be separated or rearranged for
special applications.  The manufacturer rates them at 500 milliampere-
hours.  (AAA-cells are 800 mA-h; N-cells are 650 mA-h.  See previous 
posting about alkaline-cell capacities.)

YEP!  These little suckers are great for those spots where you really
need a tiny cell.  I used to use these for model rocketry hacks.  Two
of these cells, one 3v flashlight bulb, a white plastic-bag parachute,
a few Estes "C" or "D" engines, and a paper towel center-tube (with
balsa fins glues on) would make a dandy night-time UFO.  A flashlight
bulb illuminating a 5-foot parachute, drifting at 2000 ft. will look
down-right eenie on a dark night!
