Talking Allow Me to Clarify

What I mean to say is that a vessel connected to shore power when loads are present should "never" use a multi stage charger as a maintenance charger. The reason for this is that most of the multi stage chargers are keyed on voltage. Hence when a connected system experiences a load such as a refrigerator which will momentarily drop the voltage, the charger will revert to bulk charge. By the type equilibrium voltage has been restored and the refrigerator stops cycling the process is ready to repeat. The batteries thus receive consecutive blasts at very high voltage when they don't really need it. The result is battery boiling.
