A system is provided for charging a battery with an AC adapter. The system includes a first closed loop electrical path between the battery and the AC adapter. The first closed loop electrical path includes a first monitoring circuit for monitoring at least one first parameter of the system and a control circuit for dynamically adjusting the AC adapter output to the battery in response to the at least one first parameter exceeding an associated predetermined threshold. The system includes a second closed loop electrical path between the battery and the AC adapter. The second closed loop electrical path includes a second monitoring circuit for monitoring at least one second parameter of the system and a protection circuit responsive to the at least one second parameter exceeding an associated predetermined threshold for protecting the system until the AC adapter reaches a predetermined value.
