PT, I think the OP wants to go away and think some. BTW,
"Flooded jars start to taper on charging at 85% SOC" is not correct. You have forgotten my ugly graph! :(
The SOC when Absorption starts is a variable. A higher charging rate (amps/bank AH) means battery voltage will rise quicker and bulk ends at a lower SOC--could be 65% or anything really. With a lower charging rate Bulk might not end until 90% or so SOC.
Mex likes a high enough charging rate that battery voltage spikes immediately to near Vabs and amps taper from the start. That being the fastest recharge and so the least gen time.
However, the max charging rate can be limited by the battery spec, say 27% in one case. No matter, anything over 30% has little time advantage over 30%'s time since the battery just can't do its chemical change any faster. (except Lifeline AGMs somehow)
