Ryobi 40V Lithium-Ion Battery
The alternating red/green LED sequence is the charger's diagnostic code for a defective battery pack. This is caused by the internal BMS detecting a 'deep discharge' state where cell voltage has dropped below the safety floor, or an internal cell group has failed, causing a voltage delta that makes the pack unsafe to charge.
