ABSTRACT:
A battery charger having an integrated battery charge indicator that is readily visible when a battery pack is connected for charging. The battery charge indicator is on a visible outer surface of the housing of the battery charger to indicate a state of charge of the battery pack. The indicator may include a series of light emitting diodes with one LED that is illuminated when the battery pack is charging and will flash if something is wrong with the battery pack. The housing can preferably accommodate more than one configuration of battery packs with the indicator being visible when various battery packs are attached for recharging.
