Well what is strange is that there is very little visible sulfate on the plates. It has been staying in the mid 14's for at least 5 hours each day.
But it is not getting the daily 15.3v USbattery recommended "finishing" charge, out of deference to the AGM and my inability to always be around to flip switches or test SG in the afternoon.
Just checked again. Taking 2.07 amps to hold 15.5v
1.265, 1.270, 1.260. Electrolyte less 'warbly' looking. bubbling more vigorously than before. A shadow inches from the solar panel. Don't know how much longer I can keep voltages in this range.
