Featherweight tracker, what color LED equals fully charged?

I have done this...

“Adjustable battery charger for the LiPo batteries used in the Featherweight GPS. To charge the the 400 mAhr Tracker battery, set all the DIP switchs to "off" except for the 400 mA DIP switch, plug the battery into the compatible connector, and connect the charger with a micro-USB cable (not supplied) to any USB outlet, such as a car charger or portable USB charger.”

Now the standalone charging station shows a red light and a blue light, this is the initial charging, how do i know when its fully charged?

Hard to see but one led is red the other blue, solid not flashing or anything.

Red power status.
Blue charging. When blue turns off, fully charged.
