A method of applying pulsation energy to an online battery backup system including the steps of sampling at least one voltage sampling circuit to monitor a float voltage drop across the terminals of each battery unit within a plurality of battery units, selecting from among the plurality of battery units the unit having the greatest float voltage drop, operating a pulse generation circuit to apply pulsation energy across the terminals of only the selected battery unit, and ceasing to operate the pulse generation circuit in response to a predetermined trigger. A generally corresponding method may be performed on each battery cell within the plurality of battery units. Also, battery pulsation systems for an online battery backup system may include a pulse generation circuit and a controller for selectively applying pulsation energy across the terminals of a selected battery unit or battery cell.
