E) IMPORTANT NOTE ABOUT BATTERY SOURCES
Whenever the load is turned on, it can be drawing power from the batteries. Therefore, if the batteries are not
simultaneously being recharged, or if charging will not be available for an extended period, it is recommended
that the load be shut off to prevent complete discharge of batteries.
