Have you tried totally disconnecting all batteries then overnight charging them individually? Of course when reconnecting them, carefully clean (sandpaper or wire brush) all terminals, cable ends, and grounding point stud.
To keep my four 12v engine start batteries at peak charge, I have a battery maintainer on all the time. A good maintainer won't overcharge batteries, and it goes into "float" mode which pulses after the bulk charge phase is complete. That adds years to battery life.
