Wfco replaced today. Will get data in a few weeks..

You might be working with "100% charged" 50 ampere hour batteries or maybe even less. That's what sulfate masking of plates does for a living.

I've seen 5 ampere hour group 27's. Boy they sure do charge (and discharge) fast.

Sorta like starting at a 2-quart can without a label and declaring "Well whatever it is -- that's dinner"

Run your gravities so you can avoid looking like Chief Inspector Clouseau :)
