Abstract
A method for controlling a battery includes operating a lithium- and manganese-rich (LMR) battery within a first voltage window defined by an upper cutoff voltage threshold and a lower cutoff voltage threshold; monitoring a battery capacity of the LMR battery; and in response to the battery capacity of the LMR battery falling below a predetermined battery capacity, changing the first voltage window to a second voltage window by reducing the lower cutoff voltage threshold by a predetermined voltage value.
