.....at which time the doctor spins around and walks out the exam room door.
Some of you have "espn" Diagnosis via long distance guesswork.
The batteries have had every opportunity to sulfate and at best a wimpy limp wrist attempt at recovery. GC220s do not have car jar battery .050" plates.
Check with a hydrometer. Not to 1.275 gravity junl the battery.
BUT WAIT! THERE'S MORE!!!
Load test 6 cells in series.
Have the distributor load the series cells to 200 amperes and hold there for 30 full seconds. Did the batteries crash?
It shore is embarrassing to folks jumping around and waving madly to have the batteries go another two to three years. One thing a professional learns - amateurs and wrench zombies never test. "Whelp it's outta warranty changher out.
There is NO WAY a ready-to-fail battery is going to pass a gravity and cranking amperes load test"
