1. A battery-life-extension charging system, comprising:

  • a monitoring component configured to measure a direct current (DC) output current delivered by the charging system to a battery, wherein the DC output current is a function of an existing charge status of the battery;

    a timing component; and

    a charge control system in communication with the monitoring component and the timing component, the charge control system configured for;

    obtaining at least one of a time measurement from the timing component and a charge measurement from the monitoring component;

    based on the at least one of the time measurement and the charge measurement, determining at least one of a time to complete the charge mode cycle and a charge to complete a charge mode cycle, each tailored to achieve a desired charge status of the battery; and

    based on at least one of the determined time and the determined charge to complete the charge mode cycle, transitioning to a select one of a number of DC output voltage settings until the determined time to complete the determined charge mode cycle has passed or the charge to complete the charge mode cycle has been provided, wherein the DC output voltage settings include at least an eco-float output voltage setting, a refresh output voltage setting, and a boost output voltage setting.
