I have a Red Kiwi branded Ego 650 mah battery that wont turn on. I put it on the charger and the tri-color led go's through its cycle and shows that it is charging. The charger led shows red that it is charging but never turns green and if I remove the battery it will not turn on at all now. Just wondered if there may be something I'm overlooking . Tried a different charger also, thanks all
