Abstract
A separable series of secondary cells is connected across a charge circuit upon the application of supply potential. When the charge potential level upon a selected portion of the secondary cell series attains a predetermined magnitude, the selected portion is disconnected from the charge circuit. When the charge potential level upon the remainder of the secondary cell series subsequently attains a predetermined magnitude, all of the secondary cells are reconnected in series until the charge potential level upon all of the secondary cells of the series attains another higher predetermined potential level at which time the charge circuit is disabled.
