That would be ok if you only want a boolean, charged or not charged. I assumed the OP wanted a numeric value of how charged the batteries are. Maybe I could be wrong.

Ideally yes I would like a measurement of how charged they are, but if that's super impossible and hard, then maybe ill just settle with off or on. IDK

You could get a charger that does give you the percentage and read the LEDs from the display.
