Abstract: Battery pack chargers described herein for charging a battery pack include a battery pack receiving portion, a power control module, and a controller. The battery pack receiving portion receives and interfaces with the battery pack. The battery pack includes one or more battery cells. The power control module is configured to provide power to the battery pack receiving portion. The controller is connected to the power control module. The controller is configured to provide a charging current to one or more battery cells of the battery pack using a stepped charging profile. The step charging profile includes a first charging current level. The first charging current level is greater than a predetermined maximum charging current for the battery pack. The controller steps down the charging current to a second charging current level when a voltage of the one or more battery cells increases to a predetermined voltage value.
