Battle Born Charging
This might answer some recent questions. The table is not accurate wrt to the BB comments--don't go by it by the table itself. Wade through the questions and answers to get the true picture. Tak...

Ok but when is it "full"? That picture actually says to charge it until it reaches the target voltage and stop.
That would be at the end of the Bulk stage/start of the Absorption stage.
BB says to go another 20-30 minutes after that to get to full.
And are either of those the same as when amps taper to 4a per 100AH? Not the first, since that is when amps are just starting to taper.
I remain confused.
EDIT--when you reach Vabs, amps are still high so there is some voltage drop between battery and charger. You have to be sure you are reading battery voltage, which will still be under your 14.4 charger voltage because of that voltage drop. It is not easy at that point to measure true battery voltage while you are still charging.
The way to tell you are at the start of Absorption is when amps start to taper. This is "close enough" to when you reach Vabs to use as your marker. if you wait until battery voltage is 14.4, same as charger voltage, amps will be down to zero so no voltage drop.
