All I know is everything works on shore power using a WFCO power center with NO battery in it.
A dead battery (zero volts) won't take a charge without desulphation (thus the 4 stage charger) since there are no free ions in the electrolyte. It "should" act like its not there, not a dead short.
I did only get a C+ in Physics though...
Maybe someone here got an "A"?
