mWH is correct, as the capacity of battery is mAH.

Thanks. I don’t know why I confused myself and I try to use the correct terminology. Was going to correct myself a second time but I didn’t think anyone read any of the few posts I made. I think I least got the numbers right.

No, it's the other way around. When we speak about capacity, we are talking about mWh. But you should have said mAh instead of mA ;) And yes, you've got the numbers right.

Best regards,

@Moderators

Thanks for moving my last post, but ...

At the new location, I guess it is misleading, because it is out of context. It was really intended as a reply in exactly this thread in the Montana 7x0 forum. I just wanted to say that it probably generally leads to wrong results if we believe the pure theory and the capacity ratings (although I have done the measurements I mentioned using another device). In other words, I just referred to the behavior of another device to give a general answer to the OP's question in this thread.

Thank you very much, and best regards,

Themistokles
