25%Red LED| The 25% Charge LED will slowly pulse “on” and “off” when the
battery is less than 25% charged. When the battery is 25% charged, the 25% LED
will go solid and the next LED will begin to pulse.
50% Red LED| The 50% Charge LED will slowly pulse “on” and “off” when the
battery is 25% – 50% charged. When the battery is 50% charged, the 50% LED
will go solid and the next LED will begin to pulse.
75%Orange LED| The 75% Charge LED will slowly pulse “on” and “off” when the
battery is 50% – 75% charged. When the battery is 75% charged, the 75% LED
will go solid and the next LED will begin to pulse.
100%Green LED| The 100% Charge LED will slowly pulse “on” and “off”, when the
battery is less than 100% fully charged. When the battery is fully charged,
the Green LED will be solid, and the 25%, 50% and 75% Charge LEDs will turn
“off”.
