The batteries need a slight rest, and a full meal with an overflowing belly, to get them back to 100%. That usually means 14.8V to 15V in Absorption charging mode, with a dumb charger, until the battery gets full, gets topped off, and levels out at 15.0V at the terminals, while feeding it slowly... Once it's full, you manually need to stop feeding it. Could be by timer, could be by you monitoring it until you see 15.0V at the terminals, but when full it's time to shut everything charger wise down and stop feeding it. That's a top charge.

not sure what you mean by "levels out at 15v at the terminals". if i take a voltage reading while charging, it will read whatever the charger is putting out. so the only way to see where the batteries are at is to shut down and then check. and an absorption charge is a constant voltage charge, so there is no ramping up of the voltage to 15v... that happens during bulk. so i'm not sure how to do what you're suggesting? does it have to do with it being a dumb charger? i.e; does absorption here refer to what is called bulk charge with a 3-stage charger? please explain, thanxx!
