"ON" LED on, "LOW" LED blinking: 11.1-11.5V charging voltage, low-charged battery, charge immediately. 4. "Low" LED on, "Middle" LED blinking: 11.6-12V charging voltage, medium-charged battery, better to charge soon. 5. "Middle" LED on, "Full" LED blinking: 12.1-13V charging voltage, medium-charged battery, better to charge. 6. "Full" LED on, "Good" LED blinking: 13.1-13.9V charging voltage, good battery, fully charged. 7.
