I just got my radio gear, and was charging the batterys (RX and TX). The TX (Futaba 6AX Computer) was showing at 10.0V.


I plugged both the RX and TX into the charger, and the LED red lights came on. I believe this is indicating that it's charging. How will I know when they are fully charged? Will the lights go off?

Charger model is: Futaba FBC-8B(4)

Thanks!
