"Floating" or "standby use" suggests no activity. Rv converters that do 14.4, 13.6, and 13.2 have their 13.6 for camping when on shore power with some activity, and use the 13.2 for "storage"
On solar with flooded batts, once batts were true full early afternoon, I tried 13.2 but as soon as any small load came on, the Trimetric showed negative amps until the system stabilized at 13.2 again. With it set at 13.6, it held. I figured from that, converters have their 13.6 for the same reason.
Battery specs do not seem to cover for "after the absorption stage when you are still camping".
