Sterling Power products recommend the following for 12 volt batteries:
Open lead acid: 14.8 volts
Sealed lead acid/AGM: 14.4 volts
Gel: 14.1 to 14.4 volts, as recommended by manufacturer
all with a float voltage of 13.6 volts.
I wonder if you are confusing equalise with the de-sulphation mode that some chargers have where the battery is taken for a controlled time to 15 volts or so.
As an aside I used for six years or more Freedom Leisure sealed lead calcium batteries. Documentation
indicated they could be equalised at 14.6 volts, so I adjusted my Victron charger
accordingly. They were remarkable in having a very high internal resistance when fully charged. Even if I re-cycled the charger, after they had been charged it was difficult to get the 420 a/h bank to draw more than 1 amp with 14.6 volts applied. No energy was ever wasted therefore & they never got really warm.
