Besised simple straight (cylinder) rods...we have found "lobed" ones,
etc. We do have a complete (I assume) dry cell battery from our most
recent project (soil remediation in downtown San Diego)...with a paper
outer layer (cover). Am tempted to dissect it...to see all the
layers...and get a better understanding...but, guess I probably
shouldn't.
