Balmar smart gauge and 10 hour AH testing
So this guy was selling an open box Balmar smart gauge on fleabay. They are expensive and I go by voltage to gauge my batterys by that. Well he had a make offer price so I lowballed @ $140. He didnt ...

Just take notes and keep going. It will take hours if the batts are any good. Beware of single decimal point voltages. Can be misleading when they "round up". If you have a meter that reads to two decimal points you can get a better idea if 12.3 means 12.35 or if 12.4 means 12.35.
Battery temperature changes can mean different voltages. So will SG readings change. IMO ignore all that because the margin of error in those won't change the big picture you are after.
EDIT--that gizmo is not smarter than you. Some folks on here have been led astray by believing their AH counters and SOC meters, when they should have been checking their batteries. :(
This ten hour test (which might not take that long) will tell you the truth. Then you can calibrate the meter if it can be calibrated.
