The batters are four week old Energizer Lithium, I suppose one could be bad, but they're pretty decent batteries.
I did change the charge parameters to max 5500 as the manufacturer suggest just below 5600. After charging both batters yesterday, I was able to get a max charge on both. However run times remain to be seen. I'm going swap out the batteries just to see what happens.
