1. A passive battery charging control system devoid of active electrical control elements for charging a battery that comprises an anode fluid contained in an anode compartment, wherein the passive battery charging control system comprises one or more passive electrical control elements configured to limit the charging state of the battery; and wherein the level of anode fluid during operation of the battery is limited by at least one of the control elements; and
wherein the control system further comprises a plurality of current collectors, wherein the current collectors and the one or more passive electrical control elements together are configured to limit the charging state of the battery only when the anode fluid reaches a desired maximum level within a corresponding anode compartment; and wherein at least two current collectors are integrated with a U-shaped anode tube.
