Interesting that the manual says the batteries should bubble at the end of the finish stage. If finish means the end of stage 3 ie float voltage then that's new to me. If instead it means during equalization then that is normal. And they do recommend equalization every 30 days. It's not clear to me as the chart shows both float and equalization. They also state to avoid contiuous float if charged for more than once a week.
Pretty sure they mean bubbling during the tail end of stage 3. Float voltage is a lot lower and should not bubble.
That graph to me is only the charge cycle, showing the 3 phases, and the last phase does hit the equalize voltage but then immediately terminates charge. Now I see what Lester means by charge termination being dV/dT - they're waiting for the voltage to no longer rise during phase 3 before stopping charging.
So I'm interpreting all this data to mean that normal charging always hits equalize voltage, or at least until it doesn't rise anymore, and an actual equalization holds that higher voltage for 1-2 hours.
I'm going to set the battery profile to the lower setting (4A finishing) as that is still in-spec per trojan. Not as good as 2A with the battery tender recommendation, but better than 6A.
