If you run _exactly_ the same test under the same conditions. Same temperature, same test duration, same XO, then it might be possible to compare the current voltage, to the SOC and make a fast assessment. The battery voltage is dependent on a lot of different variables and those will need to be held constant. The profiles you are about to generate will tell us if this is possible. > I'm also trying to get some really bad but functioning batteries to test > them. Don't have them yet.

Are you going to do it on 15 different XO's? That procedure is fine for the charge files. -- Richard A.
