When the battery is fully charged (greater than 90%), the top three
LEDs illuminate. If the battery capacity is between 66% and 90%, the
second and third LED illuminate. The third LED illuminates if the
battery charge is between 33% and 66%.
If any Battery Charge LEDs are red, see pages 34 and 35 for more
