But the only way to know for sure is to install a 'coulomb counter' meter, charge them up, and then run them down into a substantial load (such as the fridge). A coulomb counter will tell you the actual Amp-Hours which the batter pair was able to deliver.

I have found this one to be reliable, although it does add another phantom load right at the batteries: https://www.amazon.com/AiLi-Battery-.../dp/B07FGFFHC6
