Can it be used to accurately calculate the energy capacity with the advertised Ah? My 18v advertised batteries measure 20v with no load. My 40v advertised batteries measure 40v no load. Which is incorrect?

I'll run some load tests on the "40v" batteries I own. What is the appropriate C-rate? I assume 1C is appropriate given the use cases.

My 40v 5Ah batteries have a label saying 180Wh. I'm charging them up and will run a 5Ah load (1C) to determine capacity. I assume all of the products will perform as a ratio of whatever my results are.
