Ridgid 18V 4.0 Ah MAX Output Lithium-Ion Battery
The alternating red and green LED pattern is the diagnostic lockout for a defective battery, triggered when the internal Battery Management System (BMS) fails its pre-charge safety check. This failure mode is most commonly caused by the voltage of the lithium-ion cell strings dropping below a critical threshold that the charger's logic controller deems unsafe for high-current recovery. Once the chemical potential of the cells is significantly depleted or cell impedance is out of range, the pack must be replaced as the BMS typically sets a non-volatile fault bit to prevent hazardous operation.
