Excellent. I usually charge lead-acid batteries with a constant current/voltage source. In the first stage, I charge at the recommended voltage of 14.4V to 14.8V, depending on what the manufacturer recommends, but I usually leave it at a maximum of 10% of the nominal current, or even less, for large-capacity batteries. Then, when I notice a low current consumption, I move on to the float stage, which varies between 13.4 to 13.7V, depending on the manufacturer. I always choose a slow charge in order to maintain the maximum battery life. In situations where I have not used the batteries for some time, every three months, I try to maintain the float charge for a maximum of 0.1C, 12 hours or more, the time that I notice a low current consumption, of 100mA or 50mA, depending on the battery capacity. And this charger does most likely te same, but with more current, to 1.5A limit.

Yes, that's the way to do it. Battery University recommends topping up stored batteries when the open circuit voltage drops below 12.3 V
