Try page 11 of this document : http://www.evdl.org/docs/deka-vrr.pdf Lower than you expected, no? :-\ In my experience, East Penn is pretty good about documentation. I've been using their gel batteries for over a decade and a half. You'll also find an under-load voltage:SOC chart on page 4 of that same document. Note the different curves for different loads (0.33 to 1C, 0.33 to 0.125C, and > 0.125C). For an open circuit voltage:SOC chart, see page 13. Don't forget that these last two guides are APPROXIMATE. Voltage is not a very good indicator of a battery's state of charge. A hydrometer is the way to go, but you can't stick a hydrometer into a sealed cell. A better indicator than voltage is an amp-hour or watt-hour meter.
