Allan;
Wow, that's a nightmare. All I can suggest for now is to X out some obvious

Trust your tools. As you know, low SG means the acid is in the form of lead
sulfate. Were these dry charged Surrettes? What environment and how long did
the batteries set from the date of manufacturer to the date of commissioning
the system? Even 120 day old batteries can begin to show problems
