A method for testing safety circuitry in rechargeable batter packs is provided herein by which the operation and integrity of circuits associated with rechargeable cells may be verified. A controller (103) senses current flow during cell (108) charge or discharge. The controller (103) then activates the safety circuitry and once again senses current to ensure high circuit impedance. If a fault is detected, the controller (103) notifies the user or host device. The controller (103) then decides if the fault warrants isloating the cell (108) from the terminals of the battery pack (111, 112). If such action is warranted, the controller (103) clears the current carrying path (104, 105), creating a fail condition that does not endanger the user or associated equipment.
