No, it depends on how sulphated they are how much time it takes. Can take hours and hours, or only a little time. No points given for using less time or fewer dips with an hydrometer. Do what it takes!
Doesn't matter how new the batts are. It's all about how they have been recharged recently. If several 50-90s in a row they will be undercharged and need Equalizing. Same thing if on solar for a week or so doing shallow cycle 75-95s and never quite get to true full. (Solar is notorious for daily undercharging)
It is all about what the hydrometer says once back home on shore power, when the charger says they are full and the hydrometer says otherwise--not full yet!
Always believe the hydrometer and the SG over "fake news" charger "fulls".
EDIT- Forgot to add: The SG it stops rising at is not your "baseline SG", but is lower than that. When equalizing the electrolyte heats up so is less dense and the hydrometer floats lower. Next morning when it all cools down, NOW you can see if it is at baseline SG (your SG when truly full)
