A method for charging at least one battery, includes: determining a status of at least one parameter for the battery, where the at least one parameter comprises a closeness to a desired charge level; determining that the battery is to be charged during a peak usage time period; and determining a priority rating for the battery based upon the at least one parameter, where a battery closer to the desired charge level has a higher priority rating. The battery is then charged according to it priority rating. When batteries are to be charged for an off-peak usage time period, the charge rates of the batteries are adjusted based upon the available time for the charge. In this manner, quick recharged battery availability is provided during peak usage time periods, while battery life is prolonged during off-peak usage time periods.
