What does it mean if it flashes from green to red? Does it mean it is maintaining the battery?
A C on Dec 29, 2016
BEST ANSWER: If you read the owners manual that came with the product, it shows the battery will flash from red to green when it is in maintaining mode. The time between the battery going from green to red, shows how strong how battery is and how long it can hold the voltage before needing the charger again
