** The ESR of a cell or battery is a good guide to its condition.

A fresh AA alkaline measures 0.1 ohms or lower while a tired one
measures 1 ohm or greater, a fresh 9V measures under 1 ohm. Along with a
voltage test you have enough info to match or discard used cells.

What's a good way to do that ?



** Do what ?

Test ESR or correlate it with open cct cell voltage?

ESR.
