Adjustable amperage for restoring AGMs?
I was reading in the Lifeline manual about this. They say to charge at constant current of 5 percent rated 20-hr capacity until 15.6v, then continue 4 more hours. It may reach 18v, be sure your syst...

With the linked power supply, it will work in either constant current or constant voltage mode, depending on what the load is at any given time. (In other words, the output will go to as high a voltage as it can go without exceeding the voltage setting and without the current exceeding the current setting.) Bear in mind that, for a given load like a battery being charged, voltage and current are not independent of each other; it is only possible to regulate one or the other at any given time. An analogy is a nozzle on a hose that's being fed by a pump. You can adjust the pump so that you have a given pressure in the hose, or a given flow, but you can't set both independently at the same time because the nozzle establishes a certain relation between the pressure and the flow.
To maintain, say, a 7.5A charge current, you'd set the constant current knobs for 7.5A and the voltage knobs for the maximum voltage and let the power supply adjust the voltage for you. No knob twiddling or needle watching required, other than to note when the voltage rises to the desired point to start timing.
