Pulsing Red LED
Solid Green LED
Pulsing Green LED
Explanation
The Red Charge LED will slowly pulse "on" and "off" when the battery is less than 75% fully charged.
When the battery is 100% charged, the Charge LED will be solid green.
The Green Charge LED will slowly pulse "on" and "off'' when the battery is between 75% and 100%
charged and dunng battery optimization charging. It is normal for optimization charging to occur on
a regular basis after the battery is fully charged.
