Abstract
A computer-implemented method for charging partial-use batteries may include (1) determining a discharge duration for a partial-use battery, (2) estimating an age of the partial-use battery, (3) calculating, based on the age, a partial charge voltage for the partial-use battery that will enable a discharge cycle of the partial-use battery to last for the discharge duration, and (4) floating the voltage of the partial-use battery at the partial charge voltage to prolong the partial-use battery's life. The partial-use battery may be a backup battery of a power supply that will experience a transition from a first power source to a second power source, the transition may be expected to last for a transitional duration, the backup battery may supply power to the power supply during the transition, and the discharge duration may be greater than or equal to the transitional duration. Various other methods, systems, and apparatus are also disclosed.
