[ARC5] Battery Report

[Rich Post]

I have also found that the cheap old fashioned carbon zinc cells seem to be
less prone to leakage than alkaline cells.  Like Wayne, I use the cheap
Sunbeam cells from Dollar Tree.  If I am concerned about leakage, I place
several soldered together inside a pill bottle and run leads to the outside
with wire nuts.  That is especially useful in VOMs where the original "D"
cell holder is broken or  damaged by leakage products.  The pill bottle
size is chosen to fit the "D" cell space and the wire nuts make it easy to
replace the package later.

For powering a Command set receiver, I have yet to try a simple tripler or
quadrupler off the 24 volt transformer used for filaments. Have
successfully used such a tripler for 90 volts of B+ to a farm set.  Given
the relatively limited current draw, a quadrupler might work for a Command
receiver.
