A system and method to charge a battery during a charging cycle having a plurality of portions. The method comprises generating a first charge signal during the first portion of the charging cycle, wherein the first charge signal is based on a charge-time parameter. The charge-time parameter correlates a charge time period of the charging cycle to (i) a state of charge of the battery and/or (ii) a charge storage level corresponding to an amount of usage time of the battery. The method further includes applying the first charge signal to the battery during the first portion of the charging cycle, and, in response thereto, charging the battery to provide a state of charge and/or (ii) a charge storage level corresponding to an amount of usage in or within the charge time period of the charge-time parameter.
