An information handling system comprising a processor, a battery to provide power to the information handling system, an AC adapter input port coupled to the battery configured to receive an AC adapter, and a battery charger coupled to the battery and the AC adapter input port configured to identify a characteristic of the AC adapter and adjust a battery charge current based upon the characteristic. The battery charger comprises an adapter identification subsystem coupled to the AC adapter input port configured to identify the characteristic and provide an adjustment current, and an adjustable charger coupled to the adapter identification subsystem and the battery, configured to set the battery charging current based upon the adjustment current. The AC adapter identification subsystem comprises an adapter identification circuit coupled to the AC adapter input port configured to identify the characteristic, and a microcontroller configured to provide the adjustment current to the adjustable charger.
