Yes.
The equalization process can partially/completely reverse "light" sulfation.
Charging and the equalization process for the Crowns is a little different than typical:
Essentially, after fully charging the battery to 7.26V and the current dropping to 12A, you are supposed to hold the 12A current for 3.5-5 hours until dV/dt flattens, i.e., voltage stops raising over time or increases negligibly.
Equalization just extends that time by 3 hours.
So, rather than a typical CC/CV charge profile, the Crowns want a CC/CV/CC profile.
Standard charge summary:
Charge to 7.26V
Hold 7.26V until current drops to 12A
Hold 12A until voltage stops increasing (about 3.5-5 hours)
For equalization, you just extend the 12A phase for an additional 3 hours.
This is likely going to be very challenging to accomplish because few chargers work like this. To equalize, you'll likely need to baby sit it and keep increasing the absorption voltage as needed to maintain 12A. Eventually, you'll find what the battery peaks at. It's likely going to be something around 8.1V - and I wouldn't personally allow it to go higher than that. Also, you should monitor battery temperature. If the battery exceeds 110°F, terminate equalization charge and allow to cool completely before additional charging.
Once you've established the equalization voltage (where 12A peaks), you can select that for future equalization operations rather than baby-sitting it.
Crown's don't say anything about float. I would personally choose 6.8V.
My supplemental recommendations are based on procedures recommended by Trojan and Rolls for their batteries.
