• Solid Red: Battery is charging.
• Flashing Green: Battery is 80% charged. This allows users to quickly resume work without waiting for a full charge.
• Solid Green: Battery is fully charged.
• Flashing Red: Battery is too hot/cold or faulty. The charger will wait for the battery to reach an acceptable temperature before charging, or indicate a fault.
