All Li-Ion charging circuits will not allow the battery to be charged if the voltage drops below a certain point. This is because the battery can become damaged and dangerous. What you are seeing, sounds like this.

For some circuits, once this is triggered, there is no way to change it. This is the case for a laptop battery. It is possible that it is also the case for the Aura HD. But, I do remember someone reporting something similar. They pulled the battery and charged it a little bit by some other method. When they reinstalled it, the charge level was above the cut off and the battery was charged and seemed to work OK. I don't know if it lasted as the report was a while ago.

I DO NOT recommend doing this. The maximum and minimum charge voltages are set to prevent the battery from being damaged and becoming dangerous. And by dangerous, I mean explosive. I remember seeing videos of some laptops exploding a few years ago because of faulty batteries.

I doubt if the device can detect if the battery is not original. For that, there is usually a circuit built into the battery. I think it will need more than three wires. But, it might be able to detect enough of the battery characteristics to determine if it is a suitable battery.
